Abstract
Unique systems, methods, techniques and apparatuses of a gate driver are disclosed herein. One exemplary embodiment is a gate driver comprising a first and second DC rail, a first converter arm including a first and second semiconductor device, a second converter arm including a third and fourth semiconductor device, an inductor, and a controller. The controller is configured to open and close the primary switching device by operating the semiconductor devices so as to transmit power between the gate driver and a gate of a primary switching device. The controller is configured to transmit a gate signal to the primary switching device by closing the second semiconductor device, then opening the second semiconductor device and closing the fourth semiconductor device in response to the gate of the primary switching device receiving power with a voltage greater than or equal in magnitude to the voltage of the second DC rail.
