| Summary: | Abstract This letter presents a circuit for powering cascode gate driver circuits with super‐junction (SJ) MOSFETs in a bridge‐leg. The cascode gate driver gives inherent MOSFET intrinsic diode deactivation, and the bridge‐leg incorporates an inductive turn‐on snubber which controls the charging currents into the MOSFETs’ output capacitances. The cascode driver circuits and snubber inductor are configured such that the gate‐drive energy is derived from the power stage. |
