[Abstract]:A miniature photovoltaic energy storage converter based on interleaved four-switch Buck-Boost (FSBB) topology is proposed. The converter has the advantages of wide input voltage range, small voltage ripple and high maximum power efficiency of solar cells. Very suitable for single solar cell maximum power acquisition and energy storage. In this paper, the working principle of the energy storage converter under interleaved control strategy is explained, the steady state performance of the converter is analyzed, the expression of the input voltage ripple of the converter is deduced, and the main working waveform is drawn. The small signal model of photovoltaic energy storage converter is established, the stability of the system is analyzed, and the design method of compensation network is given. Finally, the validity of the new topology application is verified by the principle prototype.
