Abstract

This paper describes an AC voltage regulator using AC chopper and auxiliary transformer which is series connected to main input. Detail design of the AC regulator, logic and PWM pattern of the AC chopper is described and three-phase AC regulator using two single-phase AC choppers with V connected three-phase transformer configuration is proposed for three-phase application. The proposed three-phase system has advantages of system cost due to reduced switch number and gate driver circuits, size and weight because it uses a series compensated scheme. The proposed AC regulator has many advantages such as fast voltage control, high efficiency and simple control logic. Experimental results show that it can be used as step-down AC voltage regulator for power saving purpose very efficiently.
带辅助变压器的交流斩波串联补偿式交流稳压器的研究
本文介绍了一种用交流斩波器和辅助变压器串联在主输入端的交流稳压器。介绍了交流稳压器的详细设计、逻辑和交流斩波器的PWM模式,并提出了采用两个单相交流斩波器和V接三相变压器的三相交流稳压器的方案。所提出的三相系统由于减少了开关数量和栅极驱动电路而具有系统成本优势,由于采用串联补偿方案而具有体积和重量的优势。所提出的交流稳压器具有控制速度快、效率高、控制逻辑简单等优点。实验结果表明,它可以作为降压式交流稳压器,达到非常有效的节电目的。
