Abstract

DC drive systems controlled by pulse-width modulation (PWM) techniques are expected to replace the conventional phase-controlled systems. This is due to their simple control, high reliability, low cost and fast response. This paper presents the performance of a single-phase DC drive system controlled by uniform PWM full-bridge DC-DC converter. Two different uniform PWM control techniques are considered; PWM with bipolar voltage switching and PWM with unipolar voltage switching. The overall system is simulated using PSpice where the different modes of operation, circuit voltages and currents and current harmonic spectrum are presented. The motor performance characteristics such as current, speed and torque are also presented and discussed.
