    • A converter is provided which is capable of avoiding adverse flow of an electric current from an output side of a voltage to an inductor and having a small loss in the electric power. In a converter 1, the source of an FET 11 and the drain of an FET 12 are connected to one end of an inductor L1 while the source of an FET 13 and the drain of an FET 14 are connected to the other end of the inductor L1. The sources of the FETs 12 and 14 are connected to each other. The cathode and the anode of a diode D3 are connected respectively to the drain and the source of the FET 13. After transition has occurred from a state that the FETs 11 and 13 are OFF to a state that a ON/OFF switching of the FET 11 is allowable and the FET 13 is OFF, the FET 13 is maintained at OFF. During this time, the FETs 11, 12, and 14 are turned ON/OFF individually so that an output electric current is generated that flows through a storage battery 4 between the drain of the FET 13 and the source of the FET 14. After the output electric current has been generated, the maintaining of OFF of the FET 13 is released.

The FETs 11, 12, 13, and 14 serve as switches. Then, the FETs 11, 12, 13, and 14 are turned ON/OFF individually so that a voltage applied by a battery 3 is converted. When voltage conversion is to be terminated, OFF-state of the FET 13 is maintained. Then, during the time that the OFF-state of the FET 13 is maintained, an electric current is reduced that flows from the drain of the FET 13 through a storage battery 4 to the source of the FET 14.
