摘要

提出了一种电流控制电流源型单位功率因数脉宽调制整流器。三个输入线电流被独立控制，以获得瞬态低振荡的正弦电流。直接控制功率因数，容易实现统一功率因数运行。输出直流电压通过改变交流输入参考电流的幅值来调节。由于采用了电流控制方法，所提出的整流器具有良好的稳态运行和瞬态动力学特性。给出了PWM整流器和控制电路的完整分析，并讨论了设计指南。在一台1.5 kVA样机上进行了仿真和实验，验证了理论结果和设计方程

A current-controlled current source type unity power factor PWM rectifier

A current-controlled current-source-type unity power factor PWM (pulse-width-modulated) rectifier is proposed. The three input line currents are controlled independently to obtain sinusoidal currents with low oscillations during transients. Power factor is controlled directly, and unity power factor operation can readily be achieved. Output DC voltage is regulated by varying the amplitude of the AC input current references. The proposed rectifier exhibits excellent steady-state operation and good transient dynamics, a result of the current control method used. A complete analysis of the PWM rectifier and control circuitry is given, and design guidelines are discussed. The theoretical results and design equations are verified by simulation and experiments on a 1.5 kVA prototype unit.<>
