변압기를 사용한 정현파 입력전류 Multi-Level Converter
A Sinusoidal Input Current Multi-Level Converter Using Transformer
초록
This paper is proposed a sinusoidal input voltage Multi-level AC-DC Converter using transformer. In this paper Multi-level PWM Control converter which controls input current by combining buck Converters together to improve input current characteristic, and confirmed its validity throughout simulation and experiment. This method, which is multiplying and duplicating output of converter of equal capacity, is able to control unit power factor of input current, reduce the problem caused by high frequency switching, and apply to high power converter because filter is not necessary.
