| 摘 要： | 针对二极管不控整流和相控整流电流波形畸变严重、谐波分量大、功率因数低等问题,建立了三相PWM整流器的低频等效数学模型,设计了电压、电流双闭环PI控制器,制定了合理的PWM控制策略,并通过实验对整流器模型、控制器和控制策略进行了验证。实验结果表明,本文设计的整流器交流侧电压和电流波形基本同相,即网侧功率因数高。说明PI控制器的稳定性较高,控制策略设计合理。

| Abstract: | In order to solve the problems in uncontrolled diode rectifier and phase-controlled rectifier such as current serious distortion,multi-harmonic and low power factor,a low-frequency equivalent mathematical model of three phase PWM(pulse width modulation)rectifier is established and the voltage-current dual loop PI(proportion integral)controller and,a reasonable PWM modulation strategy is designed based on the model in this paper.In addition,the model,controller and modulation strategy are verified through actual experiments and it is shown by the experiment results that AC-side voltage and current waveforms are almost in the same phase,that is higher AC-side power factor.In other words,PI regulator and control strategy are practicable and reasonable. |
