The Research of Three Phase Voltage PWM Rectifier Based on Variable-Structure Control

摘要：

Considering the poor dynamic performance and the uncertainties of the parameters of three-phase PWM rectifiers, this paper study the mathematical model of 3-phase PWM rectifiers and proposed the sliding-mode variable structure control. It can make system quick, steady and have a robust control performance against the uncertainties of the parameters. Consequently the current wave of electricity net side is ensured being sine, the power factor is approaching unity. Simulative and experimental results indicate that the variable structure control improves the dynamic performance of PWM rectifiers and strengthens the system robustness.
