Abstract

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
