本文研究了光伏逆变器的需求及未来发展趋势。然后提出了一种高效的双模谐振变换器作为光伏逆变器的MPPT平台。在考虑光伏板特性的情况下，对所提出的变流器的运行特性进行了详细的分析。在光伏板上的实验结果表明，所设计的变换器可以很好地作为MPPT平台，并且在模式转换过程中不会发生窜穿现象。此外，2kW DC/DC级的加权效率约为97.7%。
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 2kW DC/DC stage is around 97.7%.
