Maximum Power Tracking Control of Photo-voltaic using the Two Phase with Combined for Step-up Chopper

2상 2중 승압형 쵸퍼에 의한 태양전지의 최대출력추적제어

This paper is shows the configuration of the maximum power tracking control of Photo-voltaic and battery charge system. Up to now, the chopper system had the problem which a battery become a short life by reason of discontinuity of output current and its energy reduce. But in this paper, We propose the chopper system which maintain the successive output current and at the same time, control the maximum output location by change time-ratio using tracking of energy variation that occur because of the varied volume of insolation per a day and temperature.
