Power Factor Correction for Three- Phase AC-AC Buck Regulator
ERJ. Engineering Research Journal
This paper presents a new configuration of a three-phase AC-AC buck regulator to operate with a three phase inductive loads with a reduced number of controlled switches. It has a simple control with excellent performance. The proposed circuit has high efficiency for adjusting AC power; because it is composed of fewer switches and DC snubbers. The proposed regulator restrains more harmonics of output voltage and the input current flows continuously, thus a nearly unity input power factor isdoi:10.21608/erjm.2014.66937 fatcat:p7noisxb7jbbzfffgsynhgns6u
