摘要

分析了一种用于太阳能光伏直流微电网的双有源桥串联谐振DC - DC变换器。由于高开关频率和低开关损耗，这些转换器特别吸引可再生能源应用。该分析由傅立叶级数等效电路组成。此外，稳态响应显示了电流只依赖于相移调制。设计并讨论了MPPT算法。最后给出了用PSIM软件对500w样机的仿真结果。

Series-Resonant DC–DC Converter for Solar Photovoltaic Non Isolated Applications

This paper analyzes a Dual Active Bridge seriesresonant DC–DC converter for solar photovoltaic DC microgrid. These converters are particularly attracted for renewable energy applications due to high switching frequency with low switching losses. The analysis is composed of the equivalent circuit using Fourier series. Besides, the steady-state response is shown where the current flow depends only on the phase shift modulation. MPPT algorithm is designed and discussed. Finally, the simulations results using the PSIM software for a 500 W prototype are shown.
