摘要
研究了一种带可逆单相PWM整流器的交流异步电机伺服系统,分析了其工作原理,并进行了系统实验,结果表明该系统不仅获得了伺服系统的高性能,而且整流器输入电流为几乎不含谐波的功率因数基本为1的正弦波,能量可在电网和伺服系统之间双向传递。
An induction moter servo system with reversible single phase PWM rectifier is studied,the working principle is analysed and the system experiment is carried out. The result shows that not only the servo system performance is high but also the input current of the rectifier is almost sinusoidal in unity power factor without harmonics. Furthermore, the energy could flow bidirectionally between the power source and the system.
