Novel sinusoidal converters with high power factor

This paper proposes a novel sinusoidal converter which improves input power factor and input current waveform without any complicated switching modulation such as a pulse width modulation or a complicated feed-back control. It is composed of a full bridge diode, a pair of capacitors, a pair of inductors and a pair of switching devices. The configuration and control strategy are both simple, however, the sinusoidal converter effectively reduces reactive power and harmonics included in an input line current. Excellent behavior of the proposed converter is verified by theoretical analysis and experimental results
