提出并分析了一种基于再生直流缓冲器的新型脉宽调制降压-升压型交流斩波器。与以前的升降压交流斩波器相比，使用再生直流缓冲器消除了导致功率损耗的交流缓冲器。实验结果表明，该方案具有良好的交流斩波器稳态性能，与理论分析结果相吻合。
A novel pulsewidth modulation buck-boost AC chopper using regenerative DC snubbers is proposed and analyzed. Compared to the previous buck-boost AC choppers, AC snubbers causing power loss are eliminated using regenerative DC snubbers. Experimental results show that the proposed scheme gives good steady-state performance of the AC chopper, which coincides with the theoretical results.
