Abstract

A power module is adapted to be connected to a voltage source and to supply power to a load. The power module includes a power transistor; and a gate controller for driving the power transistor. The gate controller includes a gate transformer, and an impulse generator that extends a negative drive phase of a gate voltage to the power transistor relative to a positive drive phase of the gate voltage to the power transistor.
