【摘要】 针对传统三相电压型PWM整流器抗负载扰动能力不强的缺点,采用了一种基于功率守恒的负载电流前馈的控制策略,以抵消负载扰动的影响。同时将粒子群算法应用于整流器的PI参数优化设计中,提高了整流器的性能。对整个系统进行了仿真和实验验证,取得了较好的效果。更多还原

【Abstract】 This paper introduct the principels of traditional three-phase voltage source PWM rectifier(VSR).For the traditional three-phase voltage source PWM rectifier has no enough ability to anti-load disturbance,it uses a control of load current feedforward based on power conservation,to offset the impact of load disturbance.And the PSO algorithm is desigined to set the controller parameters of PI,and improve the performance of the rectifier.Then the simulation and experiment obtained good results.更多还原
