Improvement Effect of Input Current of Boost Type One Main Switching Element Rectifier Withour Using Feed Back Control

Abstract

Generally, a conventional boost type rectifier with one main switching element has any complicated control such as pulse width modulation (PWM) control or feed back control in order to improve an input power factor and an input current waveform. However, the input current waveform and the power factor of the conventional boost type rectifier can be essentially reduced to some extent without using the complicated control. And also, there is not clearly studied operation of the conventional boost type rectifier without using the complicated control, as well as not clearly studied harmonics of the input current waveform. Hence, this paper studies in detail the conventional boost type sinusoidal rectifier without using the complicated control by theoritical analysis and experimental results.
