A single-phase soft-switched series-resonant ac chopper without auxiliary switches is presented. The presented single-phase ac chopper is configured by a series-resonant conversion without cycloconversion and auxiliary switches. The presented single-phase ac chopper is a series resonator with four main switches to configure adaptively the resonant voltage(More)
This paper analyses and designs a zero-current-switching single-phase high power factor voltage-doubler rectifier. The proposed rectifier combines the conventional pulse-width- modulation technique, soft commutation technique and instantaneous average line current control to promote the circuit performance. Comparison with conventional boost rectifier, the(More)
