Active clamping circuit can effectively suppress the overvoltage of series-connected insulated gate bipolar transistor (IGBT). However, long duration operations and frequent actions of active clamping circuit would lead to high losses of the circuit and IGBT, which seriously imperils the efficiency and safety of the system, especially in the applications of high voltage IGBT (HV-IGBT). In this paper, a novel active clamping circuit with status feedback is proposed for series-connected HV-IGBTs… CONTINUE READING
