摘要： A solar power generation system includes photovoltaic modules electrically coupled to each other for generating DC power having a voltage at least as large as a minimum threshold voltage but no greater than a maximum threshold voltage. The system also includes a DC-AC power converter including a plurality of semiconductor switches for converting the DC power to AC power for transmission to a power grid. The minimum threshold voltage is based at least in part on grid voltage requirements, and the maximum threshold voltage is based on a voltage rating of the power converter.
