Abstract :
A low cost analog MPPT technique is proposed in this paper for high power efficiency in photovoltaic systems. 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 solar panels. Experiment results show the proposed technique can rapidly track the MPP with a high tracking effectiveness of 97.3%. Furthermore, the proposed system can supply a grid-connected inverter for providing AC power.
