摘要
介绍了三相大功率PWM整流电路的系统结构和工作原理 ,并对其控制方法和控制电路进行了研究。在此基础上 ,研制了一台 10 0kW实验样机。实验结果表明 ,该整流电路具有输入功率因数高、对电网谐波污染小、工作可靠等优点 ,可用作大功率不间断电源的输入整流电路。
The system configure and operation principle of three phase large capacity PWM retifier are introduced,and its control method and circuit are analyzed. A 100kW prototype is manufatured according to them. The experiment results indicate that the PWM rectifier has the characteristics of low harmonic current and high input power factor,and can be used as the input rectifier of large capaity UPS.
