Since the transformer is designed to accept AC mains directly as the input, no rectifier or mains frequency filtering circuit is required. This, together with the high switching frequency, allows the design of small-size and high-efficiency AC regulators for practical use. An experimental 50 W ...

The implementation of unity power factor in the front end rectifier is investigated. The unity power factor operation is obtained by using current vector controllers in the synchronous reference frame. The determination of the synchronous reference frame quantities is derived from the actual values of ...
proposed a rectifier-less ac/dc converter using buck-boost converters [1]. Eguchi et al. developed an inductor-less ac/dc converter by combining a Cockcroft–Walton circuit with a charge pump voltage converter [2]. Distinguished from these single-input single-output (SISO) converters, some...
The converter includes a rectifier circuit (2), choppers, circuits (14) and (20) for controlling the choppers and an input filter (3, 4, 5, 8 and 9) of LC type. The control circuits include loops for regulating the output voltages V+, V-, and currents Ih+, Ih- of the choppers,...
