| Abstract |
This paper describes a novel strategy of maximum-power-point tracking for photovoltaic power generation systems. A unique feature of this method is capability to seek the maximum power point using only a single current sensor, i.e., a Hall-effect CT. Output power of the photovoltaic can be estimated with an average value and ripple amplitude of the detected current. A conventional hill-climbing method is employed to seek the maximum power point, using the output power obtained from only the current sensor. In this paper, not only a theoretical aspect of the proposed method is described, but also experimental results are presented to prove feasibility of the method. |
