Abstract

Soft-switching gate control circuitry is disclosed. The circuitry includes a first discharge circuit coupled across a first switching device. A first control circuit, upon a first switch input signal transitioning from a disabled state to an enabled state, is adapted to cause the first discharge circuit to transition from a high impedance state to a discharge impedance state, and when a voltage across the first switching device drops below a first threshold value, cause the first switching device to transition from an off state to an on state.
