Abstract
This paper investigated the requirements and future trends for photovoltaic inverter. Then a high efficiency dual mode resonant converter is proposed as the MPPT stage for photovoltaic inverter. A detailed analysis for operation features of proposed converter is given where the PV panel characteristics have been considered. The experimental results with PV panels show that the proposed converter can function as MPPT stage well and no shoot through occurs during mode transition. Also the weighted efficiency of a 2 kW DC/DC stage is around 97.7%.
