摘　　要：由于谐振变换器在接近空载时易产生振荡,以输出电流或电压的正负作为判定依据的传统换向策略会导致变换器误换向。提出一种基于电压波动和电流下降趋势判断的换向运行控制策略,对切换时电压电流阈值参数进行设计,优化切换效果,能在变换器正反向运行时根据负载情况精确找到切换时刻点,不易发生误换向。仿真结果验证了切换控制方法的有效性。Due to the susceptibility of resonant converters to oscillations near no-load,traditional commutation strategies based on the positive or negative output current or voltage can lead to incorrect commutation of the converter.A commutation operation control strategy based on voltage fluctuation and current decline trend is proposed.The voltage and current threshold parameters during switching are designed,and the switching effect is optimized.It can accurately find the switching time point according to the load situation during the forward and reverse operation of the converter,and is not prone to erroneous commutation.The simulation results verified the effectiveness of the switching control method.
