摘要
在建筑光伏一体化(BIPV)系统中,集中式能量变换结构以大面积光伏阵列为单位,当受到周围建筑物等形成的局部阴影影响时,其输出功率大大降低,且难以完成最大功率点跟踪(MPPT)。从电路拓扑结构出发,设计了一款直流模块式变换器,该变换器增益和能量转换效率较高。最后构建实验模型验证了变换器可行性。
In the building integrated photovoltaic (BIPV) system, the centrahzed energy conversion conngnrat, on uses a large area of PV array, however, it is easy to be affected by partial shadows created by surrounding buildings, leading to its output power reduces greatly, and it is difficult to complete maximum power point tracking(MPPT).This paper designs a DC modular converter based on the energy conversion configurations, which has high gain and energy conversion effficiency.Finally,the experimental model is completed and the results verify the feasibility of the converter.
