摘要： Described herein are methods and circuits for driving a power switching device of a power converter. The methods and circuits include providing a negative gate to source voltage to the power switching device during an off transition of the power switching device, wherein the negative gate to source voltage is provided independent of one or more switching element for driving the power switching device; wherein body diode conduction by the one or more switching element is mitigated; wherein a circuit connected in parallel with the gate and source of the power switching device is used to set or define the negative gate to source voltage.
