| 摘 要： | 介绍一种采用移相变压器的双桥整流器,对这种拓扑结构进行了阐述和分析,并对相移变压器的消谐原理进行了推导,得出了系统可以四象限运行,并且具有很高的功率因数的结论。运用SHE-PWM的调制思想,提出了双波段SHE-PWM调制方案,得出了具体的计算数据。实验结果证明,该拓扑结构及调制方案对电网的污染很小,具有一定的实用价值。

| Abstract: | This paper introduces a dual-bridge rectifier with a phase shifting transformer,analyzes the topology configuration,and demonstrates the principle of harmonic elimination of phase shifting transformer,draws a conclusion that the system can run in four-quadrant operation with a very high power factor.this paper also proposes a modulation scheme with dual-bands SHE-PWM applied the thought of selected harmonic elimination,and calculates the numerical solution of SHE-PWM equations. The experiment results prove that the topology and modulation method takes on an applicable value with little pollution to power grid. |
