A low cost maximum power point tracking (MPPT) technique is proposed in this paper for high power efficiency in photovoltaic systems to track the maximum power point (MPP). Compared to the various studies of the MPPT topologies, the proposed implementation is achieved by monitoring the power slope conditions of solar panels. The post grid-connected DC-AC inverter helps feedback the transformative power for providing AC power. Experiment results demonstrate the rapid tracking operation of MPP and a high tracking effectiveness of 97.3%.

A compact-size analog maximum power point tracking (AMPPT) technique is proposed in this paper for high power efficiency in the photovoltaic (PV) system. Combining existing MPPT approaches, we present a fast and accurate tracking performance. Here, a wide-range current multiplier, which tracks the maximum power point (MPP) in the solar power system, is implemented to detect the power slope condition of the solar panel. Experimental results show that the proposed technique can rapidly track the MPP with a high tracking accuracy of 97.3%. Furthermore, the proposed system can connect to the grid-connected inverter to supply ac power.
