Double Conversion Uninterrupted Energy System With Rectifier And The Inverter Integration

Abstract

This paper presents the design, implementation and experimental results of a double conversion uninterrupted power supply (UPS), with integration of the rectifier and the inverter stages. The system is composed by a rectifier and an inverter, which employs a single-pole strategy for the switching modulation. The main system characteristics are: the control assembled with commercial integrated circuits, and the unified circuit of the rectifier and the inverter. Theoretical analysis, operation principle, and topology details are presented and validated through experimental results.
