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.

Abstract: Unique systems, methods, techniques and apparatuses of semiconductor failure prognostication. One exemplary embodiment is a power converter comprising a semiconductor switch and a converter control system. The converter control system is configured to turn on the semiconductor switch, measure a first voltage and a current during reverse conduction, estimate junction temperature of the semiconductor device, turn off the semiconductor device, measure a second voltage after turning off the semiconductor device, determine a resistance value using the second voltage measurement, determine an expected resistance value, predict a failure of the semiconductor device using the resistance value and the expected resistance value, and transmit a semiconductor device failure warning.
