PROBLEM TO BE SOLVED: To provide a power distribution circuit for a solar cell module capable of enhancing efficiency of output power by smoothening a level difference which appears in current versus voltage characteristics when output of a part of the solar cell module of a photovoltaic power generation system is reduced due to the shade or the like.SOLUTION: Between solar cell modules M1, M2 connected in series, a part of output power from the solar cell module M1 whose power generation output is large is distributed to the solar cell module M2 whose power generation output is small via fly-back transformers T1, T2 to improve the current versus voltage characteristics by complementarily and periodically switching ON/OFF of first switching elements S11, S12 and second switching elements S21, S22. |
