四象限PWM整流器的设计与仿真
资料介绍
给出了四象限电压型PWM整流器（VSR）在dq坐标系中的简化数学模型。采用固定开关频率的双闭环直接电流控制策略,分析了电压和电流PI调节器参数的确定方法,指出交流侧电感和直流侧电容的选取对整个系统的影响,给出了设计方法,在Matlab/simulink下建立仿真模型。仿真表明：给出的调节器设计方法和电路参数设计方法正确,且可使能量双向流动,实现了能量回馈,对四象限PWM整流器的研制有重要的理论指导意义。
A simplified mathematical model of four-quadrant PWM rectifier in dq coordinate system was given.The fixed switching frequency of pairs of closed-loop direct current control strategy was used in this paper.The method to determine the voltage and current PI regulator parameters was analyzed,the selection of the AC-side inductance and DC side capacitor on the entire main circuit was proposed,the design method was given,and the simulation model was built with Matlab/simulink.The simulation results show that the given regulator design method and circuit parameter design method is correct,and allows two-way flow of energy to achieve the energy feedback;the simulink has an important theoretical guide to four-quadrant PWM rectifier-style devel...
