Experimental analysis of power factor correction using magnetic energy recovery switch

Abstract

Power factor correction is one of the major issue in electrical power system for maintaining its high efficiency. Low power factor leads to draw extra power from the source to fulfill the same power demand of load. This paper presents a technology named as Magnetic Energy Recovery Switch (MERS) for improving the power factor by compensating reactive power. MERS consists of four semiconductor devices (with antiparallel diodes) connected in full bridge configuration and a DC capacitor. Simulation study is conducted with resistive- Inductive load (to create the reactive power demand) and results are compared with and without MERS, whereas experimental analysis confirms the potential and effectiveness of the proposed technology for power factor improvement.
