High Voltage Diode for DSCP
The high voltage diode blocks the high voltage during IGBT off state. The connection of this diode between driver and IGBT
is shown in the following schematic.
Gate resistors
The output transistors of the driver are MOSFETs. The sources of the MOSFETs are separately connected to external
terminals in order to provide setting of the turn-on and turn-off speed of each IGBT by the external resistors R
As an IGBT has input capacitance (varying during switching time) which must be charged and discharged, both resistors will
dictate what time must be taken to do this. The final value of the resistance is difficult to predict, because it depends on
many parameters as DC link voltage, stray inductance of the circuit, switching frequency and type of IGBT.

Application Hints
The gate resistor influences the switching time, switching losses, dv/dt
behaviour, etc. and has to be selected very carefully. Due to this
influence a general value for the gate resistors cannot be
recommended. The gate resistor has to be optimized according to
switching behaviour and over voltage peaks within the specific
circuitry.
By increasing R
current of the free-wheeling diode will diminish.
By increasing R
inductive peak over voltage during turn-off will diminish.
In order to ensure locking of the IGBT even when the driver supply
voltage is turned off, a resistance (R
