© 2015 IEEE. This paper first presents a maximum power point efficiency analysis of the conventional direct connection of PV panels to a battery. Next, an improved shunt maximum power point tracking (MPPT) which integrated a half-bridge converter with a full-bridge load is proposed. The configuration is designed such that the PV panel voltage equals the sum of capacitor voltage and battery. This capacitor voltage is controlled to achieve the MPPT of the PV panels. Some experimental results are reported to verify the proposed concept and analysis.
