Abstract

A switch apparatus includes a semiconductor power switch connected for delivering current while driven by a gate drive voltage and an adaptive gate drive unit connected to a gate of the power switch. The gate drive unit is configured to select one of a plurality of pre-determined time functions for a gate drive voltage, and to deliver the gate drive voltage to the gate of the power switch according to the selected time function, thereby driving the power switch to deliver current within a pre-determined slew rate envelope.
