Abstract
In one aspect of the disclosure, a variable-current gate driver includes a plurality of inputs for receiving pulse-width-modulation (PWM) control signals transmitted from a processing system. Current sources controlled based on the pulse-width modulation (PWM) signals are coupled to respective gates of at least two transistors of a hybrid switch in the power module (PM) including different semiconductor technologies. The current sources are coupled respectively to at least one other non-gate terminal of the transistors. The current sources provide the slew rate control of the PM using variable current values to compensate for differences in the at least two semiconductor technologies in real-time to reduce switching losses and maximize efficiency.
