Abstract
According to one aspect, embodiments of the invention provide a gate driver comprising a level shifter circuit configured to be coupled to a controller, to receive control signals from the controller, each control signal having a voltage with respect to a control ground, and to redefine the voltage of each control signal with respect to a chip ground to generate redefined control signals, a gate driver chip coupled to the level shifter circuit and configured to be coupled to at least one semiconductor device, the gate driver chip further configured to provide bipolar control signals to the at least one semiconductor device based on the redefined control signals, and at least one power source configured to provide at least one positive supply voltage to the gate driver chip and at least one negative supply voltage to the gate driver chip and to the chip ground.
