摘要

投资一种新型、高效的最大功率点跟踪器(MPPT)可以使光伏发电成本降低30%。这种功率变换器目前正在开发中,实现了前馈输出电流控制器作为跟踪算法。典型的MPPT的DC-DC功率变换器利用了与零跃迁开关相关的高效高频操作。因此,输出滤波器仅由蓄电池及其布线的组合组成。由此产生的功率转换器适合在制造过程中集成到标准PV板中。在12.5 V的低电池电压和21.00美元的组件成本下,MPPT的输出功率范围效率为96%。

Economical, PV maximum power point tracking regulator with simplistic controller
A 30% cost reduction of photovoltaic generation can be brought about by the investment in a novel, highly efficient maximum power point tracker (MPPT). Such a power converter is currently under development, implementing a feedforward output current controller as tracking algorithm. The DC-DC power converter, typical of a MPPT, exploits the efficient high-frequency operation, associated with zero-transition switching. Thus the output filter only consists of the combination of a storage battery and its cabling. The resulting power converter is suitable for integration into standard PV panels during manufacturing. The efficiency of the MPPT is 96% for a range of output powers at a low battery voltage of 12.5 V and a component cost of US$21.00.<>
