摘要
提出了一种基于四桥ＰＷＭ交流控制技术的新型移相器。它采用互补式ＰＷＭ控制方式和四桥叠加结构的交流控制技术，具有调节速度快、控制简捷灵活、注入电压谐波畸变率低等显著特＊点。对所提出移相器的工作原理进行了理论分析，并通过计算机仿真证明了所得结论的正确性。
This paper, presents a phase-shifter based on four-bridge PWM AC controller which uses duty cycle control and a four-bridge structure, to vary the trasmission angle rapidly and* continuously, and features faster response, easier control, higher reliability and lower harmonics. The theoretical analysis and simulations on computer verify the conclusions .*
