It is desirable that the rectifier that is an ac‐to‐dc converter, have the characteristics of fast response and the wide range of the output voltage control, and the sinusoidal source current waveform. In this paper, a step up/down output voltage PWM‐controlled rectifier is proposed. The features of the proposed rectifier are as follows. (1) The calculation of pulsewidth is based on the geometrical technique and the source current can be inphase with the source voltage. (2) The output voltage is controlled from about zero to more than the maximum value of the source voltage. The aforementioned features are clarified by simulation and the steady‐state characteristics are discussed. Further, these results are verified in experiment using the microprocessor‐based control system.
