3 Phases-3 Devices AC Voltage Regulator With Quasi-Zero Switching
This paper presents a novel voltage regulator with sine waves, which only consists of 3 switch devices in 3 phases configuration. Simplest chopper control is adopted to operate the system in quasi-zero switch state (quasi-ZCS switching on and quasi-ZVS switching off) by means of reasonable parameter-match without zero-switching branch circuit assisted. Analyses and experiment results are presented to prove the high efficiency and its appliance prospect
