Abstract

A control technique which generates high-quality sinusoidal output voltage form a single-phase pulse-width-modulated (PWM) inverter suitable for uninterruptible systems is presented. A scheme for combining the deadbeat control with a current source compensator is proposed, and the control mechanism is analyzed. A current source compensator is used to compensate the voltage drop at the firing instant of a triac-controlled resistive load. The PWM is determined at every sampling instant by the proposed algorithm. Simulation results show that the scheme can produce nearly sinusoidal waveforms for nonlinear loads
