基于关断延迟的共源共栅GaN器件结温在线提取方法

In this article, a method to extract the junction temperature of cascode gallium nitride (GaN) devices based on the turn-off delay is proposed for the first time, together with a possible circuit implementation. We described the method theory at first, which showed good applicability even at low gate-resistor values, allowing avoidance of self-sustained oscillations and extra losses. The circuit i...
