Abstract :
The authors present and summarize key HVMCT (high-voltage MOS-controlled thyristor) characterization results gathered to date as they relate to HV MCT dynamic performance during zero voltage switching. HV MCTs have been developed and tested in a zero-voltage soft-switching test circuit. The devices have static breakdown voltages of 3000 V and turn-off losses that are comparable to those of fast GTOs rate for 2500 V peak. However, the onstate losses of the HV MCTs are slightly higher assuming 8 dies can be paralleled to match the current handling capability of the GTO.<>
