Abstract

A compact-size analog maximum power point tracking (MPPT) technique is proposed in this paper for high power efficiency in the photovoltaic system. Here, a wide-range current multiplier, which tracks the maximum power point (MPP) in the solar system, is implemented to detect the power slope condition of a solar panel. Experimental results show the proposed technique can rapidly track the MPP with a high tracking efficiency of 97.3%. Furthermore, the proposed system can supply the grid-connected inverter for providing AC power.
