摘要
针对单相两电平脉宽调制(PWM)整流器在电力机车辅助变流系统的应用要求,从数学模型出发分析其控制策略,着重分析网侧电流比例谐振(PR)控制器的实现方式。通过Matlab仿真和实验验证了该控制方式能够实现网侧功率因数接近1、直流侧电压稳定、交流侧电流正弦性好、动态响应快等控制目标。
According to the application requirements of the single phase two level PWM rectifier in the auxiliary con- verter system of electric locomotive, the control strategy is analyzed based on the mathematical model, and the real- ization mode of the network side current proportional resonant(PR) controller is mainly analyzed.The Maflah simula- tion and experiments show that this control method can achieve the goal of controlling the power factor close to 1, stabilization of DC-link,low harmonic distortion of AC current, fast dynamic response and so on.
