Abstract

This paper introduces a family of power converters for power recycling during the burn-in test of synchronized UPSs. The main feature of the new circuits is their ability to draw from the UPS and inject into the utility grid a low total harmonic distortion (THD) current with no need of active harmonic current elimination. The new circuits operate at constant frequency and are regulated by conventional PWM, using dedicated PWM integrated circuits developed for power supplies. Circuit operation, mathematical analysis, design example and experimental results are provided in this paper
