The Control of Single Phase AC/DC Converter by using Binary Combination

바이너리 조합에 의한 단상 AC/DC 컨버터의 제어

This paper proposed the single phase multi-level PWM AC/DC converter using binary combine which controls input current by combining buck converters 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, has the advantage of being able to control unit power factor of input current and reducing of the problem caused by high frequency switching, and appling to high power converter because filter is not necessary etc.
