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.
