摘　　要：通过对有源箝位谐振直流环节逆变器换流过程的分析 ,提出了采用母线电压双幅控制和箝位电压平均值反馈相结合的策略 ,省去了母线短路控制 ,大幅度降低了直流环节的损耗。仿真和实验结果证明了该控制策略的可行性。An average clamping voltage feedback combined with two amplitude link voltage control is adopted to the Active Clamped Resonant DC Link Inverter (ACRDCLI) It omits the controlled short circuit time and greatly reduces the DC link losses By detailed analysis of commutation process, this paper gives the loss comparison between the traditional method and the proposed one Simulation and experimental results are given to confirm the effectiveness of the proposed solution
