摘要
为了提高电压型PWM整流器的抗扰动能力,在电压型PWM整流器数学模型的基础上分析了影响整流器动态响应的2个因素,提出了一种iq不恒为0、负载电流前馈的策略,提高了系统的负载抗扰动能力,仿真结果验证了该方法的正确性。
To improve the performance of anti-disturbance for voltage source three-phase PWM rectifiers, it analyzes two factors of dynamic performance for three-phase PWM rectifiers on the base of its mathematical model, and then proposes a scheme which iq doesn＇t equate zero permanently and the load current is in feedforward. At last, the validity of this strategy is verified with Matlab/Simulation.
