摘　　要：针对传统单相整流电路中低功率因数对电网产生较大谐波干扰等问题,为使整流电路性能可高效节能运行。文中从对单相电压型PWM整流器的原理及控制策略分析入手,将电压外环和电流内环构成的双闭环PWM控制策略引入到中小功率的单相整流电路中,并对这种控制策略的作用机理进行详尽阐述,表明该方法的先进性。然后利用MATLAB/Simulink仿真平台搭建仿真模型,通过仿真结果验证出该方法的引入使得系统具有可网侧高功率因数运行、网侧电流正弦化、快速动态响应等优点,从而大大降低了对电网的谐波污染。To solve this problem of the conventional single-phdase rectifier circuit of low power factor on the grid havea greater harmonic interference, energy-efficient operation of the system. The text from the principle of the single-phase voltagetype PWM Rectifier Control Strategy Analysis start the voltage double-loop PWM control strategy consisting of outer and innercurrent introduced into the small and medium-power single-phase rectifier circuit, and the control mechanism of this strategywill be elaborated, indicating that the advanced nature of this approach.The use MATLAB / Simulink simulation platform tobuild simulation models, results show that this method can be introduced into the network side so that the system has a highpower factor, sinusoidal line current, fast dynamic response, etc., thus greatly reducing the harmonic pollution on the grid.
