Research on Electric Vehicle Charger Based on Voltage SourcePWM Rectifier with Direct Power Control

  • 摘要: 针对电动汽车充电器,提出了基于电压型PWM整流器的改进的直接功率控制策略。首先,介绍了PWM整流器的拓扑结构;然后分析了传统的六区间直接功率控制系统的基本原理和控制特性;为了改善控制特性,在传统六区间的控制方法的基础上,提出了十二区间的控制方法,并对该方法进行了详细推导和阐述,给出了在该方法定义下的开关表;最后用PSCAD对改进的直接功率控制方法进行了可行性验证,用QuartusII9.0对开关表进行了仿真,发现各项数据都可以达到预期指标。

     

    Abstract: For Electric Vehicle (EV) chargers, the modified strategy of Direct Power Control based on voltage source PWM rectifier is proposed. First, the topological structure of PWM rectifier is introduced. Then the basic principle and control characteristic of traditional Direct Power Control (DPC) system with six interval divisions is analyzed, based on which a control method with twelve interval divisions is proposed to improve the control characteristics. Then this new method is deduced in detail, and the switch table which is defined by this method is proposed. Finally, the modified Direct Power Control method is validated by PSCAD, and simulation on the switch table is implemented by using of QuartusII9.0, which shows that each data can reach its predefined index.
