A series-resonant single-phase step up/down ac chopper is presented. The main attribute of the ac chopper topology is the fact that it generates an output ac voltage larger or lower than the input ac one, depending on the instantaneous duty-cycle. This property is not found in the classical ac chopper, which produces an ac output instantaneous voltage always lower than the input ac voltage. The presented...
A series-resonant single-phase series-resonant AC chopper 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 robes. The synthesized sinusoidal waveform (SSW) before output filter...
