Improvement Effect of Input Current Waveform of Novel Boost Type Two Main Switching Elements Sinusoidal Rectifier

Abstract

This paper proposes a novel sinusoidal rectifier which improves input power factor and input current waveform without any complicated switching modulation such as a pulse width modulation (PWM) or a complicated feed back control.
The novel sinusoidal rectifier consists of a pair of capacitors connected in series, a full bridge diode rectifier, a pair of indctors, and a pair of switching devices connected in series. Therefore, the configuration of the sinusoidal rectifier is simple. However, in spite of its simplicity, the sinusoidal rectifier effectively reduces the reactive power and harmonics involved in input line current.
The excellent behavior of the novel sinusoidal rectifier is verified by theoretical analysis and experimental results.
