The adapter board builds the interface between the driver core and the IGBT module. The driver can be soldered on the adapter board or plugged into connectors. SEMIKRON offers adaptor boards for SKiM 63/93 modules. For customer specific adaptor boards please contact your responsible sales for further information. Fig. 4: Adapter board for SKIM 93 Adapter board with DC link measurement and temperature shutdown feature. The adapter board connects three SKYPER 42 LJ R with one SKiM63/93 GD module.

Soldering Hints The temperature of the solder must not exceed 260°C, and solder time must not exceed 10 seconds. The ambient temperature must not exceed the specified maximum storage temperature of the driver. The solder joints should be in accordance to IPC A 610 Revision D (or later) - Class 3 (Acceptability of Electronic Assemblies) to ensure an optimal connection between driver core and printed circuit board.

Do not apply switching signals during power on reset. 4.4 Gate driver signals - primary The inputs have a Schmitt Trigger characteristic and a positive / active high logic (input HIGH = IGBT on; input LOW = IGBT off). It is mandatory to use circuits which switch active to +15V and 0V. The duty cycle of the driver can be adjusted between 0 – 100%. It is not permitted to apply switching pulses shorter than 1µs. Fig. 8: TOP / BOT Input A capacitor is connected to the input to obtain high noise immunity. This capacitor can cause for current limited line drivers a little delay of few ns, which can be neglected. The capacitors have to be placed as close as possible to the driver interface. In addition one can add a series resistor for even higher robustness with the consequence of a longer delay time.

Fig. 11: Gate Resistor By increasing RGon the turn-on speed will decrease. The reverse peak current of the freewheeling diode will diminish. User Side RGon By increasing RGoff the turn-off speed of the IGBT will decrease. The inductive peak over voltage during turn-off will diminish. SEC_TOP_IGBT_ON In order to ensure locking of the IGBT even when the driver supply voltage is turned off, a resistance (RGE) has to be integrated. SEC_TOP_GND SEC_TOP_IGBT_OFF RGoff Typically, IGBT modules with a large current rating will be driven with smaller gate resistors and vice versa.

Protection features 5.1 Failure management The SKYPER 42 LJ detects under voltage situation on primary and secondary side, short circuits and errors from the external protection circuits like over temperature or over current. Any error detected will force the output PRIM_nERROR_OUT into low state. The IGBTs will be switched off (IGBT driving signals set to LOW). The input side switching signals of the driver will be ignored. The driver is reset after 30µs with the following conditions: No error root cause for 30µs (Reaction on customer side has to be done within that time) Switching inputs low for 9µs (also within the 30µs) Following failures are indicated by the failure output Under supply voltage situation on primary and secondary side Short circuit in the IGBT bridge Generic failure input of the secondary side failure input: Over temperature, over current Primary side error input © by SEMIKRON 2014-09-17 – Rev08 12 / 20 Technical Explanations SKYPER 42 LJ R The failure management of SKYPER 42 LJ R can be modified according to the application. SKYPER 42LJ offers the possibility I.e. for MLI topologies to indicate error conditions without switch off. The driver sends an error signal over a separated transformer to ensure safe and fast error indication in each switching condition. The switch off procedure can than done by the controller according to each application.

The dead time is not added to a dead time given by the controller. The highest dead time dominates. Example: Controller > driver Controller < driver Controller no dead time Driver without dead time Controller dead time 4µs 1µs No dead time 2µs SKYPER dead time 2µs 2µs 2µs No dead time Total dead time 4µs 2µs 2µs 2µs It is possible to control the driver with one switching signal and its inverted signal. No error signal will be generated when signals are overlapped. PIN Signal Function Specification X10:02 PRIM_CFG_SELECT Interlock set up HIGH (VP) = No interlock LOW (GND) = Interlock 2µs 5.3 Short pulse suppression This driver circuit suppresses short turn-on and off-pulses of incoming signals. This way the IGBTs are protected against spurious noise as they can occur due to bursts on the signal lines. Short or high noise pulses don’t affect the driver on the controller side. The filter time can be set up by the customer. When using the digital filter the tolerances are very low over the hole temperature range. The analogue setting can be chosen for ambitious applications like MRI which require very low jitter values. The delay times are different depending on the setting.

The reference voltage VCEref may dynamically be adapted to the IGBTs switching behaviour. Immediately after turn-on of the IGBT, a higher value is effective than in steady state. VCEstat is the steady-state value of VCEref and is adjusted to the required maximum value for each IGBT by an external resistor RCE. It may not exceed 10V. The time constant for the delay (exponential shape) of V CEref may be controlled by an external capacitor CCE. It controls the blanking time tbl which passes after turn-on of the IGBT before the VCEsat monitoring is activated. Fig. 16: Reference Voltage ((VCEref ) Characteristic V 15 10 VCEref VCEstat 5 VCE VCEsat 0 turn on instant t tbl After tbl has passed, the VCE monitoring will be triggered as soon as VCE > VCEref and will turn off the IGBT.

The reduced di/dt reduces the voltage spike above the collector emitter in the short circuit case. The soft turn-off time can be adjusted by connection an external resistor RSoftOff .
