| Abstract: | 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. |
