摘要
分析了单相电压型PWM整流器的工作原理,建立了整流器的数学模型。采用瞬时直接电流控制策略,确定了电压外环电流内环的PI控制器参数。利用Matlab/Simulink仿真平台对系统进行了仿真分析,设计了1 kW的实验样机,得到了满意的充电曲线和功率因数校正结果。
In this paper, the working principle of single-phase voltage-type PWM rectifier is analyzed, and a mathematical model of the rectifier is established. By using instantaneous direct current control strategy and policy, the parameters of PI controller which contains voltage loop and current loop are determined. The system is simulated and analyzed by using the Matlab/Simulink simulation platform. A 1 kW experimental prototype gave satisfactory charging curves and power factor correction results.
