The Drivers are separated in two temperature classes -25C for the 2ED300C17-S and -40C for the 2ED300C17ST. The electrical function and the mechanic dimension are in both version similar. Only if there is a different in the types the 2ED300C17-ST is called. The 2ED300C17-S is one of the EiceDRIVERTM driver family. (eupec IGBT controlled efficiency DRIVER). The 2ED300C17-S IGBT driver is designed for use with eupec IGBT modules of the 1200V and 1700V series. Functions of the 2ED300C17-S such as the "soft shut down" or the VCEsat reference curves have to be adapted to the individual modules. This is described in the following chapters. The 2ED300C17-S is designed for applications with high safety and reliability requirements and aims for power ratings of 75kW to 1MW. To offer high interference suppression, +15V is generally used for control. The entire logic processing is also done with +15V. The integrated transformer is separated into three sections: Two pulse transformers and a dual channel DC-DC switch mode power supply. These are designed such that they offer lowest coupling capacitances and high isolation stability. The 2ED300C17-S is additionally equipped with a feed-back "Sense" input. This input can optionally be connected with the active clamping or di/dt and dv/dt control. The clearance and creepage distances comply with VDE0110 and VDE0160 / EN50178 and are designed for pollution degree 3. Materials of the transformer meet requirements of UL94V0. Protection degree IP00. To protect from undefined switching of IGBTs in case of a gate-emitter short circuit of another IGBT, the supply voltage VA;B+; VA;B- is internally monitored in the driver for short circuit currents. In case of a gate-emitter short the secondary circuit is interrupted and thus the primary voltage maintained. Exclusion clause: The datasheet is part of the eupec IGBT driver 2ED300C17-S. To guaranty safe and fault free operation it is necessary to have read and understood this datasheet. The eupec IGBT driver 2ED300C17-S is only intended for control of eupec IGBT modules. The company eupec GmbH cannot warrant against damage and/or dysfunction if IGBT modules used not produced by eupec. In this context, eupec GmbH retains the right to change technical data and product specifications without prior notice to the course of improvement. www.eupec.com www.EiceDRIVER.com Page 3 Technical Information EiceDRIVERTM 2ED300C17-S Chapter: *Safety notice *General information *Exclusion clause *Contents 1. 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 1.10 2. 2.1 3. 3.1 3.1.1 3.2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 3.10 3.11 3.12 4. 4.1 4.2 4.3 www.eupec.com Datasheet *Features *Key data *Block diagram *Inputs and outputs *Pin configuration *Maximum permissible values *Characteristic values *Max. switching frequency at different rated currents *Mechanical dimensions The transformer * Safe electrical isolation Protection Class II according to EN50178 Application of the 2ED300C17-S *Power supply *Use of the internal over-current shut-down *Mode selection *Interlock delay times *Logic levels (reset; fault output) *Signal level *IGBT connection *IGBT Shot circuit / IGBT overload shut down *SSD "soft shut down" *External fault input *"Sense" input (SSD and active clamping) *Additional output voltage / buffer capacitors *Application example 2ED300C17-S General Designation and symbols Module internal gate resistors Type designation www.EiceDRIVER.com preliminary Page 2 3 3 4 5 5 5 6 6 7 8 9 10 11 12 12 13 13 14 15 16 17 17 20 23 25 25 27 28 29 29 30 32 Page 4 Technical Information EiceDRIVERTM 2ED300C17-S 1.2 Features * Dual channel IGBT driver 2ED300C17-S * For 1200V / 1700V eupec IGBT modules * VCE sat monitoring * "Soft Shut Down" for fault conditions * Save electrical isolation according to EN50178 * Integrated DC-DC SMPS * High peak output current * 15V secondary drive voltage * Short signal transition time * Optional "Sence" function * High RFI immunity 1.3 Key data Isolation testing voltage according to EN50178 protection class II preliminary Visol pulse transformer and DC/DC 5000 30 4 <670 400 +15 +15 50* -25 bis 85 -40 bis 85 VAC A W ns ns V VDC kV/s C C Max. output current: Max. output power Signal transition time Minimal pulse suppression PWM drive voltage Supply voltage dv/dt stability Operating temperature direct on driver surface Operating temperature direct on driver surface www.eupec.com IG per channel PDC/DC per channel tpd (on); tpd (off) tmd turn on and turn off Vin drive level for channel A and B Operating voltage VDC to ground dv/dt ( * during test) Top Top 2ED300C17-S 2ED300C17-ST www.EiceDRIVER.com Page 5 Technical Information EiceDRIVERTM 2ED300C17-S 1.4 Block diagram 2ED300C17-S Fault Detection preliminary EDFA VCEsat E.

The transformer 2.1 Safe electrical isolation Protection Class II according to EN50178 preliminary The safe isolation between primary and secondary side of the two transformers and the switch mode power supply is the basis for the 2ED300C17-S. Highly insulated coil wires, core insulated ferrites and a special sealing compound (UL94 V-0) are used for this purpose. The design makes sure that all windings are physically separated from each other. There are no overlapping primary and secondary windings. The winding connections are terminated directly to the pins which are cast into the housing. All that is contained in a plastic housing certified to UL 94. 16 9 1 8 Figure 2.1 Complete transformers with cores in position The transformer is designed for use in industrial and traction applications. The test voltage applied between all inputs and all outputs is 5kV AC for 1 second. The test voltage applied between the secondaries is 2.25kV AC for 1 second. (EN50178 Table18) (Individual test) The insulation test is completed by the surge voltage test stipulated by EN50178. Surge voltage test according to (EN50178 table 17) is 1.5/50s with 9.6kV. The partial discharge extinction voltage stipulated by the standard (EN50178 table19) is above 1763V crest value (type test). www.eupec.com www.EiceDRIVER.com Page 12 Technical Information EiceDRIVERTM 2ED300C17-S 3 Application of the 2ED300C17-S: preliminary 3.1 Power supply The 2ED300C17-S has an integrated DC-DC switch mode inverter, which generates the required secondary voltages. The generated voltages are for the top and bottom channel with +15V primaries each 16V secondaries. Hence the 2ED300C17-S only requires one external power supply of +15V. The 2ED300C17-S is operated on a stabilized +15V (1V) supply. It is distinguished between VDD and VDC. All inputs are switched with+15V,where VDC should be additionally stabilized by a capacitor CDC (see figure 3.1). This stabilizing capacitor CDC should be 220F minimal. All GND pins have to be connected. To prevent a ground loop there is no internal connection of the DC-DC SMPS ground and the primary electronics. 10R 1F +15V CDC 1 VDD +15V 2 VDD +15V 3 VDD +15V 4 Fault A 5 Reset 6 CA 7 IN B 8 CB 9 Modus 10 Fault B 11 IN A 12 GND 13 GND 14 VDC +15V 15 VDC +15V 16 VDC +15V 17 VDC +15V 18 VDC +15V 19 GND 20 GND 21 GND 22 GND 23 GND Note! If the driver is turned on with +15V, a low voltage fault may be tripped depending on the voltage slew rate. This will be reset after 50ms if both signal levels IN A and IN B remain Low during this time. Note! No potential difference greater than 20V may occur between VDD and VDC. Figure 3.1 Pin configuration of +15V voltage supply Note! The 2ED300C17-S features secondary under-voltage monitoring. If the secondary supply voltage drops below typical +12V or -12V, a fault condition will occur which turns off the driver and is transferred to the primary as well. www.eupec.com www.EiceDRIVER.com Page 13 Technical Information EiceDRIVERTM 2ED300C17-S 3.2 Mode selection preliminary The 2ED300C17-S features two operating functions to drive eupec IGBT modules. These are the direct mode and the half-bridge mode. * The direct mode: In this mode there is no link between the two channels of the 2ED300C17-S. Both channels IN A and IN B are working independently from each other and may both be turned on at once. The inputs IN A and IN B are switched with +15V PWM signals. The direct mode is activated by taking pin 9 "Mode selection" to GND (e.g.: pin 12/13). The inputs CA pin 6 and CB pin 8 are not connected. Note! In the direct mode the inputs CA and CB may not be connected to +15V or GND. For EMC reasons it is recommended to connect the inputs CA and CB with 470pF to GND. * The half-bridge mode: This mode generates an interlock time between the two channels of the 2ED300C17-S. I.e. there is always only one channel active. The interlock time between the switching events may be selected. This is done with the inputs CA pin 6 and CB pin 8. The half-bridge mode is activated by taking pin 9 "Mode selection" to VDD (pin 1/2/3). The inputs IN A and IN B are switched with PWM inputs. Explanation: There is always only one channel turned on. If there is a high signal on one channel, this is turned on after the interlock time has ended. If during this time there is a high signal for the second channel it will be ignored until the first turned on channel has turned off.

This minimal interlock time tTD is preset to 1,6 s. By adding a capacitance to the two inputs CA and CB this interlock time is extended and adapted to the requirements of the application. The capacitance is externally added between CA and CB to GND (see page 7 - 1.6 Pin configuration). The capacitance for the required interlock time is derived from the following table: Del. time TTD 1,6s 2s 2,4s 3.4s 4,3s 5,4s 9,6s CA / CB n.c. 47pF 100pF 220pF 330pF 470pF 1nF NOTE ! It is not permit to connect the inputs CA and CB direct to a voltage potential. NOTE ! The tolerance of the interlock delay times depends mainly on the tolerance of the external capacities. This needs to be considered when choosing the capacitors!

The switching threshold is at 8V, so the existing +15V offers itself as switching signal. 1) Mode: see chapter 3.2 2) Reset: The driver can be reset via the reset input after a fault has been indicated. The reset input is active high, i.e. a high signal activates the reset. Logic signal level is by 8V. If reset is used by the PWM inputs IN A and IN B, the reset input is inactive and pin 5 (Reset) has to be permanently connected to GND If both PWM signals are "low" for more than 39ms the driver is reset. * Logic outputs The driver core recognizes short circuit current faults of the IGBTs and faults of the supply voltage. Additionally the 2ED300C17-S features an external fault input. If a fault is detected through the VCE sat monitoring, an under-voltage or the external fault input, the driver core is immediately turned off. With these faults on the secondary side, the IGBT is shut down via a soft turn-off. Each fault is stored until a reset signal on Pin 5 is present. The reset is also activated when the input signal on both channels is low for more than 39ms. Indication of a fault occurs in any case via a common fault line on the logic output FAULT. The fault is brought out twice via Pin4 and Pin10. These outputs are configured as open collector. The outputs can operate at up to 20V and can switch a maximum of 20mA . If a fault is recognized the internal transistor switches and pulls the fault output to GND. +15V +15V 1 VDD +15V 2 VDD +15V 3 VDD +15V 4 Fault 5 Reset 6 CA 7 IN B 8 CB 9 Modus 10 Fault 11 IN A GND Figure 3.4 Fault output Note! The fault outputs are internally connected. There is only one fault output - doubled up. www.eupec.com www.EiceDRIVER.com Page 16 Technical Information EiceDRIVERTM 2ED300C17-S 3.5 Signal level preliminary In both the direct mode and the half-bridge mode the input IN A of the 2ED300C17-S controls channel A, and input IN B controls channel B. The inputs feature a SchmittTrigger and an active high logic. A high level turns the IGBT on and a low level turns it off. The two signal inputs may be operated with a maximum of 20V per channel. Brief negative peaks of equal voltage will not lead to damage of the inputs. The switching threshold is at +8V to GND. The input impedance is 3.3kOhm for each channel. For long cables it may be necessary to connect an external burst suppression network. Note: The 2ED300C17-S features a minimal pulse suppression. Pulses with less than 400ms will be suppressed by the driver. 1 VDD +15V 2 VDD +15V 3 VDD +15V 4 Fault 5 Reset 6 CA 7 IN B 8 CB 9 Modus 10 Fault 11 IN A 12 GND 13 GND 14 Vdc +15V 10H Figure 3.5 Input signal level PWM B PWM A 10H 3.6 IGBT connection The 2ED300C17-S features two independent channels to drive the IGBTs. It is possible to drive individual IGBTs, single IGBT-modules or IGBT-modules connected in parallel. The maximum size of the IGBT-modules depends mainly on the IGBT input capacitance and on the switching frequency. This dependency is described on page 9 for KE3 modules. When considering the gate currents, note that these are not determined by the external gate resistors alone. Many eupec IGBT modules have internal gate resistors (See chapter 5). Additionally, the 2ED300C17-S features a low output impedance. Hence a gate current calculated via the external gate resistor will never be realized in practice. An approximation for the drive power and peak current can be achieved with: *Driver power P G = f V GE 2 C ies 3 P = P DD + PG * Max. driver current f = switching frequency Cies = input capacity (datasheet) PDD = driver dissipation IG max = V GE R G (min) V = 30 V at 15 V RG(min)=RG extern+RG intern Page 17 www.eupec.com www.EiceDRIVER.com Technical Information EiceDRIVERTM 2ED300C17-S *Gate connection preliminary The gate of the IGBT is connected to Gate A or Gate B via the external gate resistor. The associated auxiliary emitter is connected directly to the COM outputs. The gate output voltage is 15V with respect to COM A and COM B (considering chapter 3.1). By utilizing the external gate resistors it is possible to realize turn-on and turn-off with different gate resistances. Additionally to the gate resistor a gate-emitter resistor and gate clamping should be used. These would be placed between the gate and the aux. emitter. As RGE a resistor <10kOhm is recommended. The gate clamping is done with Zener diodes or suppressor diodes with a break-over voltage of less than 18V. These diodes prevent the gate voltage to rise to inadmissible levels through parasitic effects (e.g. Miller capacity). The external gate resistors are defined in the eupec IGBT datasheet.

This is used to recognize a short circuit and then shut-down. For the optional function of DVRC or active clamping the connection to the collector is also required. For the short circuit shut-down function the auxiliary collector is connected to VCEsat A or VCEsat B. To block the high DC-link voltage during shut-down a diode Dx with high reverse blocking voltage has to be connected between the collector and the "Vce sat" input. The reverse blocking capability of these diodes should be higher than the IGBTmodule voltage (1200V/1700V). Further the diode has to follow the switching frequency and therefore has to be accordingly fast. Two or three diodes in series is an option to achieve the required blocking capability. Application and adjustment of the short circuit shut-down is described in detail in the next chapter 3.7.

The 2ED300C17-S measures the VCE voltage while the IGBT is turned on. If the VCE rises above the preset reference voltage during this period, a fault is triggered and the IGBT is turned off via the internal soft shut-down. For eupec IGBT-modules with NPT and FS-technology the soft shut-down reduces the voltage over-shoot by a slower turn-off. *The reference curve is only adjustable via an external RSX and CSX . With RSX the reference voltage is set and with CSX the reference time. The resistor and the capacitor are connected between RC A and COM A or RC B and COM B . The reference time elapses directly with the turn-on of the respective driver side (See figure 3.7.2) V Vref Reference curve Gate A 45 Gate A 44 COM A 43 COM A 42 VA+ 41 VA- 40 Sense A 39 RC B 38 Vce sat A 37 E.

The maximum VCE voltage at the comparator will be 10V. With the turn-on of the IGBT the VCE voltage drops to its threshold value depending on the load current IC. To suppress commutation effects during turning on the IGBT there is the settable reference curve Vref. This drops, depending on the external CSX and RSX network, from 16V to the set voltage level. If the VCE voltage rises above the reference voltage at any time, a fault is tripped and the driver is locked. The various different operating conditions are depicted in the four cases below. If the fault occurs, the IGBT is turned off via the SSD (Soft Shut Down) function. +15V +15V Fault +10V Vref +5V VCE 0V Case 1. Usual case +10V Vref +5V VCE 0V Case 2.

This network is used to set the sensitivity of the VCE SAT monitoring as required by the individual application. One has to keep in mind that this RC network is a timing function. Accordingly, reaching the reference voltage and in this connection the detection of the temporal short circuit current in the IGBT depend on the charging process of the CVCE capacitor. This can easily be defined by measuring in front of CVCE once and in comparison to this V ce sat x directly at the input. The RC combination is able to prolong the operating time till the IGBT switches off in case of a short circuit. This is to say that in addition to reference time treff (table 3.7) and SSD cycle time tSD=5s and system cycle time tSD=1s, the trigger suppression time has to be taken into account. As a standard, a value of RVCE =470R and CVCE =1nF is recommended. Should the VCE sat monitoring react too sensitively the CVCE value can be increased. This of course prolongs the trigger time of the short circuit turn-off. In a contrary case, it is certainly recommended to decrease the CVCE value or the RVCE value. One always has to make sure that the short circuit across the IGBT is switched off after 10s. DA 2x UF4007 RGA Gate A 45 Gate A 44 COM A 43 COM A 42 VA+ 41 VA- 40 Sense A 39 RC B 38 Vce sat A 37 E.

This is sensible in order to avoid destruction of the IGBT due to high voltage overshoots during turn-off. If set correctly the SSD will reduce the turn-off di/dt of all eupec IGBT products and hence the voltage overshoot during fault conditions. The "Soft Shut Down" is set with resistor RSSD. This resistor is externally connected between Sense and -16V (see figure 3.8.1). Gate A 45 Gate A 44 COM A 43 COM A 42 VA+ 41 VA- 40 Sense A 39 RC A 38 Vce sat A 37 E.

B 24 RSSD CSA RSA Figure 3.8.1 Connection of RSSD The "Soft Shut Down" has to be adapted to the IGBT type used. Since the turn-off behavior and the resulting voltage overshoot depends on the IGBT type and the construction of the entire application, the resistance of the RSSD resistor has to be found in a practical manner. As guidance one can use the module FS450R17KE3 with an RSSD = 10k. IGBT modules with a greater input capacitance Cies will need a lower RSSD value, IGBT modules with a lower input capacitance Cies will need a greater RSSD value. The dissipation of the resistor is calculated as follows: PSSD [W ] = 1024 RSSD If a fault is recognized and the "Soft shut down" is activated, the capacitances of the internal bipolar- output stage go through the charge reversal and thus the IGBT input capacitance Cies and the Miller capacitance Cres are discharged slowly. This process is limited to tSD= 4s. After this time the output of 2ED300C17-S turns off hard. The driver has to be reactivated by a "Reset" (see chapter 3.4 logic levels). www.eupec.com www.EiceDRIVER.com Page 23 Technical Information EiceDRIVERTM 2ED300C17-S preliminary Note! The "Soft Shut Down" may slightly increase the VGE. Hence the gate clamping described in chapter 3.6 IGBT Connection has to be observed. Note! eupec IGBT modules are generally designed for short circuits of up to tP 10s. With the calculation of the external network RSX and CSX make sure not to exceed this time. tP-tSD-tsys= tref tP= short circuit time IGBT 10s tSD= SSD transition time 5s tsys= system transition time 1s tref= reference time (+ Trigger suppression for the Vce sat ) Note! The "Soft Shut Down" is not 100% protection from voltage overshoots during fault turnoff! Should a short circuit occur and at the same time the natural PWM puls go to Low Level the SSD can not be commenced. This case is rare but can occur. Active Clamping will then protect against over-voltage (see 3.10). VGE 1100V IC VCE VC Figure 3.8.2: Short circuit turn-off at 1100V with SSD The short circuit turn-off depicted in Fig. 3.8.2 clearly shows the course of the Gate-Emitter voltage with SSD. www.eupec.com www.EiceDRIVER.com Page 24 Technical Information EiceDRIVERTM 2ED300C17-S 3.9 External fault input preliminary The 2ED300C17-S features an external fault input E.A and E.B. These are used to set the internal fault memory by a high gate output signal and to trigger a fault. The fault inputs E.A and E.B have an active high logic. Switching level is at 5V, so that a high signal will trigger a fault. The maximum level for the input is VA+ or VB+ referenced to the adjoining COM. This input is considered for example to detect an over-temperature and/or over-current and so to shut down the driver. Note that the inputs E.A and E.B may rise up to DClink potential! Note ! If the inputs E.A and/or E.B are not used, they have to be connected to COM A / COM B. 3.10 "Sense" input (SSD "Soft Shut Down", optional DVRC or active clamping) A special feature of the 2ED300C17-S is the ability to directly manipulate the driver output stage. This is a bipolar output stage externally accessible via the "Sense" input. This is necessary to limit the voltage overshoot through the di/dt during turn-off of the IGBTs. (see also chapter 3.8 SSD). With a additional circuit and by using the sense input it is possible to control this di/dt in every operating point during turn-off of the IGBT and hence prevents inadmissibly high turn-off voltage overshoots.

The "Soft Shut Down" has to be adapted to each module type. For this an external resistor RSSD is connected between "Sense" and -16V. (See chapter 2.8 Short circuit/over-current turn-off with "Soft shut down" ) Note! The "Soft shut down" is the standard setting of the 2ED300C17-S.
