摘要
首先解析了非正弦不平衡电压下脉宽调制(PWM)整流器交直流侧功率的组成,指出PWM整流器在非正弦不平衡电压下运行时交直流侧较难同时满足高性能的电能质量要求。在此以提高整流器交流侧输入电流质量为目的,提出一种简单、有效的控制方法,仿真和实验均验证了该方法的可行性。
The AC/DC side power components of pulse width modulation(PWM) converter running under nonsinusoidal and unbalanced voltage is analyzed,then it is point out that it is more difficult to satisfy the AC/DC side demands of high performances power quality under the conditions at the same time.In order to improve the AC side current power quality,a simple and effective control method is proposed.The simulation and experimental results prove that the method is feasible.
