Chapter 5 Protection Circuit Design - Fuji Electric
www.fujielectric.coma. Control the surge voltage with an additional protection circuit (snubber circuit) to the IGBT. A film capacitor in the snubber circuit, which is con nected as close as possibl e to the IGBT, works to bypass the high frequency surge currents. b. Adjust the IGBT drive circuit’s – V GE and/or RG in order to reduce the di/dt value. (Refer to ...
