Abstract

Due to low on-state resistance and parasitic parameters, GaN devices can cause false triggering oscillation in practical systems that will affect system performance. In this paper, an RC snubber circuit is proposed to suppress false triggering oscillation in a half-bridge circuit and the design method of the RC parameters is proposed. The proposed oscillation suppression method is simpler, easier to implement, and more effective than the active gate driver. The proposed method is verified by experiment results. And it can provide guidance for oscillation suppression design in high-order systems.
