Abstract
It is an object to obtain a photovoltaic power generation system. A photovoltaic power generation system includes multiple solar cell modules each having a different band gap and step-up voltage transformers (boosters) that receive outputs from load resistors, the load resistors being controlled to maximize outputs of the respective solar cell modules. An output voltage of each step-up voltage transformer (booster) is controlled to be a predetermined output voltage (or output current), and the step-up voltage transformers (boosters) are connected in parallel (or in series) to obtain predetermined electric power.
