Abstract
A gate driver for providing slew rate (SR) control of a power module (PM) includes input ports for receiving pulse-width-modulation (PWM) control signals transmitted from a processing system, voltage sources and gate resistors controlled by the PWM signals and having outputs coupled to a respective gate of at least one first transistor of a hybrid switch in the PM. The hybrid switch includes the at least one first transistor and at least one second transistor each comprising different semiconductor technologies. The gate driver also includes current sources controlled by the PWM signals and having outputs coupled to respective gates of the at least one second transistor of the hybrid switch in the PM. The voltage sources, the gate resistors, and the current sources are configured to provide the SR control of the PM to thereby compensate for the different semiconductor technologies in real time.
