| 摘 要： | 该文提出了串联型有源箝位谐振直流环节变器（TSACRLI）的母线电流双幅控制策略，该方案在原有的简单拓扑上，即实现了软开关，又有效降低的谐振直流环节及箝位开关损耗，改善了逆变器的输出性能。通过对换流工作过程的分析，讨论了双幅控制的实现条件，并掉控制方案进行了对照，仿真和试验有力证明了该控制方案的可行性。

| Abstract: | A novel Two-amplitude DC link current control strategy for Series Actively Clamped Resonant DC link Inver-ter (SACRLI) is proposed in this paper. On a basis of this simple topology, soft switching condition for all the devices is obtained. The power dissipation on the resonant devices and clamp switch are greatly reduced. Meanwhile the output performance is improved. 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. |
