Abstract
A variable current gate driver for a transistor includes a first current control device having a first controllable output current. The first current control device is electrically connected between a first bus and an activator of the transistor, and a second current control device having a second controllable output current. The second current control device is electrically connected between the activator of the transistor and a second bus. A controller is operatively connected to the first and second current control devices to control the first and second controllable output currents to control the first and second current control devices to control activation of the transistor via the activator. The controller is operative to control the first and second current control devices to control a slew rate of the transistor.
