新型三相四线桥斩控式整流器及控制方式研究

STUDY ON THREE-PHASE FOUR-BRIDGE SWITCH MODE RECTIFIER AND TTS CONTROL MODE

介绍了三相四线桥斩控式整流电路及其最佳输入控制模式和最佳输出控制模式，并将其与相控式整流电路进行了比较。实验表明，它有效地解决了相控式整流电路存在的功率因数低。

A three-phase four-bridge switch mode rectifier structure was proposed and analyzed.With two kinds of optimum control mode,this rectifier can obtain maximum input powerfactor,minimum input harmonic distortion,small input filter size,and improved output DCvoltage waveform.
