Charge-compensated or “super-junction” MOSFETs exhibit low on-state resistances and low switching losses. However, the reverse recovery behaviour of their intrinsic diodes and their output capacitance characteristics make their deployment as synchronous rectifiers challenging. To address these issues, a combination of techniques is investigated and evaluated in a fan-less 400V, 1.5kW BLDC machine drive inverter switching at 20kHz.
