마이크로컨트롤러를 이용한 태양광발전용 승압초퍼형 MPPT 제어기에 관한 연구

Solar cell converts sunlight into the electricity that one of the most versatile forms of energy. It has been developed and applied on residental electric power system by urbanized countries as a alternative energy source to overcome energy problem after oil shock. A DC-DC converter can be commonly used to control the power flow from solar cell to load and to achieve maximum power point tracking(MPPT). This paper describes the experimental results of the PV system contain solar modules and a DC-DC converter(boost type chopper). The experimental results show that the PV system is always operated at maximum power point of solar cells having stabilized output voltage waveform with relatively small ripple component.
