基于模型的最优开关频率与副边移相角匹配以优化光伏微型逆变器效率

In order to fulfill the requirements of high step-up, wide gain, and high efficiency in photovoltaic (PV) microconverter, an LCC resonant converter using a hybrid modulation strategy that combines variable-frequency and secondary-side phase-shift (VF-SSPSM LCC) is proposed in this article. By proposing a precise theoretical model, the most appropriate switching frequency (SF) and secondary-side ph...
