Page 9: Gate Drive Design
CMR performance of more than100 kV/µs. The OC pin of ACPL-352J is connected to the collector of IGBT T12 via a high voltage blocking diode, D5 and resistor R13. - Page 10 ACPL-352J Reference Manual Vincotech H6.5 3-Level IGBT flowPACK Module Evaluation Board During overcurrent fault condition, the IGBT is soft shut down through the SS pin and the rate of shut down can be adjusted by R14. The gate resistors (R15/R16) serve to limit gate current and indirectly control the IGBT switching times. Diode, D1 is used together with the CLAMP function to shunt parasitic IGBT Miller current during the off cycle.
