Application example for 1200V IGBT, VCEref=6,7V, tBL=2,3µs, Qout/pulse = 4µC.
Any parasitic inductances within the DC-link have to be minimized. Overvoltages may be absorbed by C- or
RCD-snubbers between main terminals (plus and minus) of the power module.
Make power patterns short and thick to reduce stray inductance and stray resistance.
The connecting leads between gate driver and IGBT module must be kept as short as possible (max. 20cm).
Gate wiring for top and bottom IGBT or other phases must not be bundled together.
It is recommended that a 10kΩ resistor (RGE) be placed between the gate and emitter. If wire connection is
used, do not place the RGE between printed circuit board and IGBT module. RGE has to be placed very close
to the IGBT module.
Use a suppressor diode (back-to-back Zener diode) between gate and emitter. The diode has to be placed
very close to the IGBT module.
The use of a capacitor (CGE) between gate and emitter can be advantageous, even for high-power IGBT
modules and parallel operation. The CGE should be approximately 10% of the CGE of the IGBT used. The
CGE has to be placed very close to the IGBT module.
Current loops must be avoided.
External boost capacitors must be placed as close to the gate driver as possible in order to minimize parasitic
inductance.
