A power converter is installed for each solar cell, and electric power having a low voltage and a relatively large electric current is input to the power converter, thereby reducing as much as possible the wiring work which greatly raises the cost of an electric power generator. For this purpose, a power converter which has a high operating efficiency and by which a low-cost electric power generator can be constructed when an unstable power source such as a solar cell is used is desired. As this power converter, a DC/DC converter is provided which supplies DC power supplied from the solar cell to a transformer by switching the DC power, thereby boosting the output voltage from the solar cell by a few tens of times to a few hundred times. The number of turns of the primary winding of the transformer is set to 2 or 3.
