The rectifier, that is an AC to DC converter, is desirable to have the characteristics of the 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 pulse width is based on the geometrical technique and the source current can be in phase with the source voltage. (2) The output voltage is controlled from about zero to more than the maximum value of the source voltage. The above-mentioned 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.
