Maximum power point tracking controller of solar cell by means of chopper system

쵸퍼 방식에 의한 태양전지의 최대 출력점 제어기의 구성

This paper discusses a maximum power point tracking controller (MPPTC) by using chopper with an adjustable input to output voltage. The MPPTC is determined by sensing only the actual voltage from solar cell array. It is simple and continuously tracks the solar cell array maximum power point regardless of the load type. Also, the system obtains protection circuit to protect overcharge and disovercharge against the battery.
