摘　　要：提出了串联有源箝位谐振直流环节逆变器 (TSACRLI)的双幅控制策略 ,该方案不仅保持了原电路结构简单 ,软开关等优点 ,而且有效降低了直流环节损耗 ,进一步提高了工作频率 ,加快了输出动态响应速度。文章分析了换流工作过程 ,讨论了双幅控制的实现条件 ,并通过对比仿真和实验证明了双幅控制的可行性与优越性。A movel two amplitude DC link current control strategy for Series Actively Clamped Resonant DC link Inverter(SACRLI)is proposed.It inherits the simplicity of traditional topology and obtains Zero Current Switching(ZCS)condition for all the devices.The greatly reduced power dissipation on the resonant link and extended high frequency operation potential are achieved by the imported scheme.Therefore the outstanding performance of the inverter is available.In this paper,detailed operation process is analyzed and critical condition to realize two amplitude resonance is discussed.Comparison between the proposed control technique and the traditional one is made to show the improved performance.Simulation and experiment verified the effectiveness of the proposed control technique.
