摘要
介绍了一种新型单相三电平高功率因数PWM整流器电路拓扑,详细分析了该电路的工作状态,推导了其数学模型。采用预测电流控制和逻辑开关状态控制作为其控制策略,经计算机仿真结果表明,该整流器能够维持直流侧输出电压稳定,并可实现高功率因数运行。
A novel single-phase three-level PWM rectifier with high power factor is introduced, the working state is analyzed in detail, and the mathematic model of the rectifier is derived. The predictive current control technique and logic switch state control for the rectifier is adopted. The simulation results show that the rectifier can work with high power factor, and the voltage of DC output is steadilized.
