摘要
高功率因数电能变换和负载电能回馈电网的实现是电力节能的关键问题。在对电压型单相PWM(Pulse-Width Modulation)整流器的拓扑结构以及其工作原理的分析基础上,提出了相应的控制方法并分别对主电路参数和PI调节器参数进行了选择和设计。基于Matlab计算机仿真软件对整个单相pwm整流器控制系统进行了建模和仿真,结果表明PWM整流器控制系统能很好实现高功率因数电能变换和电能的双向流动。
The realization of high power factor electric energy transforming and load energy return to power mains is the sixty-four-dollar question of electric power economizing, the topology configuration and working principium of the single-phase voltage-source PWM rectifier are analyzed. Then, the corresponding control method is derived also the parameters of the main circuit and PI adjustors are chosen and designed. The modeling and simulating of the whole single-phase PWM rectifier control system are derived based on the Matlab computer simulation software. The results indicate that the given PWM rectifier control system can well realize the high power factor electric energy transforming and the electric energy transmitting bidirectionally.
