Simple Construction of MPPT for PV Power Generation Using General Purpose Logic ICs

Abstract

Energy consumption of the world is steadily increasing yet, and will continue even for the future. The capital energy source is fossil fuels like petroleum and coal. Since it is finite resources, they will be exhausted someday. Furthermore, such energy source causes an environment problem. In such circumstance, solution of the problems is that adopting renewable energy, especially photovoltaic power for its easy to adaption. Under such environment, in the paper, a novel MPPT (maximum power point tracker) for photovoltaic power generation system is proposed by using general purpose logic ICs, that is simple and concise construction. In addition to application of the MPPT for the photovoltaic power, the maximum or the minimum value tracking could be easily realized and accepted for another various application.
