| 摘 要： | 分析了单周控制三相4线制3开关3电平(VIENNA)整流器的基本原理.该控制器不需要乘法器和采样三相输入电压,开关管承受电压应力为输出电压的一半,控制方法简单,并且可以物理解耦成输出并联的3路单相3电平PFC,在三相电网不对称(包括缺相状态)情况下,整流器仍能正常工作,提高了VIENNA整流器的环境适应性.

| Abstract: | A three-phase 4-wire star-connected switch three-level rectifier(VIENNA) with unity-power-factor -correction with one cycle control was analyzed.The advantage of this rectifier is that the switch voltage stress is one half of the total output voltage and it doesn't require multipliers and three-phase voltage sensors. The rectifier can be decoupled in topology to three single phase three-level PFC with output parallel-connected. When three-phase lacks input,the rectifier still has excellent PFC characteristi... |
