Resumen:

This paper presents the analysis, design and simulation of a simple DC-UPS converter with integrated back-up and automatic transition. This converter makes automatic transitions between the main AC and the battery when a failure occurs; and it delivers uninterrupted DC power to the load through two independent power sources of commercial input power and battery power. The converter has the following characteristics: automatic transition between the main and the battery, no additional control to detect failure in main, single structure, galvanic isolation, multi output voltages capability and only one switch control for two operation modes: normal and back-up. The analysis, design and simulation for this converter are presented. © 2008 IEEE.
