Uninterruptible Power Supply (UPS) Using Double Conversion Technique

Abstract

The critical loads in every vital economic sectors such as manufacturing, communication, and healthcare sector are mostly sensitive to the power disturbances. Thus, a stable, reliant and continuous power supply is highly required to maintain the equipment works in its maximum efficiency. In this study, an uninterruptible power supply (UPS) using double conversion technique is presented. UPS system acts as a backup power supply and protects the sensitive equipment from power disturbances and interruption. The simulation of designing converters such as rectifier, boost converter and inverter are presented by using computer-aided design software MATLAB. All simulation results show the UPS system able to provide continuous power supply with acceptable power quality to the critical loads.
