摘　　要：针对高频链矩阵变换器的变压器一次侧电流切换频繁时导致的电压尖峰问题,提出一种基于零矢量调节的抑制策略用于消除矢量切换处的电压尖峰,设计了零矢量的作用时间计算规则。通过所提换流策略前后的变压器前后尖峰对比实验,验证了所提方法的可行性。Aiming at the problem of voltage spikes caused by frequent current switching at the primary side of high frequency link matrix converter transformer,a suppression strategy based on zero vector regulation is proposed to eliminate the voltage spikes at the vector switching,and the calculation rules of the action time of zero vector are designed.The feasibility of the proposed method is verified by the peak contrast experiment before and after the proposed commutation strategy.
