基于双闭环的单相电压型整流器PFC非线性控制
Power Factor Correction Nonlinear Control for the Single-phase Voltage Rectifier Based on Dual-loop
摘要
Abstract
Taking the nonlinear time-varying characteristics of the rectifier,a mathematical model of the singlephase voltage rectifier was built by using the state-space averaging method.Then,based on the Lyapunov stability theory,the dual-loop controller was designed.The unity power factor of the AC-side was fulfilled by the control of the inner-current loop,and the control law of the outer-voltage loop was designed to achieve the stable of the AC-side voltage.In the Matlab/Simulink,the simulation model of the single-phase voltage rectifier was built to verify the effectiveness of the proposed control method under the disturbance of the grid voltage or the load.The simulation results show that the DC-side voltage is stable,and the grid-side current is sinusoidal and in the same frequency and phase with the AC supply voltage.关键词
