The wide band-gap (WBG) devices have received widespread attention due to their excellent characteristics like low on-resistance, fast switching speed and better thermal conductivity. However, the crosstalk problem restricts the performance of high-speed WBG transistors in bridge-leg converters. What's more, in high current converters, the crosstalk problem will become more severe. To overcome the crosstalk problem in high current converters and fulfill the WBG devices' high-speed potentials, a simple positive and negative crosstalk mitigation method is presented in this article. This method does not require extra auxiliary controlled switches and extra control strategies, and can mitigate the positive and negative crosstalk spikes. What's more, it is simple implementation, and can be easily integrated with the conventional voltage source gate drivers. The effectiveness of the presented crosstalk suppression method is proved by the simulated and experimental outcomes.
