Effect of Dynamic Advanced Active Clamping of 1SP0335 Gate drivers
Datasheets of 1SP0335 gate driver series introduce Dynamic Advanced Active Clamping(DA^2C) to suppress High Voltage during IGBT switching events.
I ask you to answer these questions about the 1SP0335 gate driver DAAC function.
1. Does DAAC function perfectly control (or cut away) high voltage over threshold voltage of each gate driver model?
--> whether the voltage on the switch(in turning off operation) is suppressed to be under the maximum available IGBT DC voltage (in case of 1SP0335-45 and 4.5kV IGBT pair or 1SP0335-65 and 6.5kV IGBT pair)
2. If RC or RDC snubbers are attached to IGBT, is there any problem with the DAAC function working correctly?
--> The existence of interaction between snubbers and gate driver DAAC function and whether the interaction interrupts DAAC function working
