PROBLEM TO BE SOLVED: To provide a conversion device that prevents backflow of current from an output side of voltage to a coil and reduces loss of power.SOLUTION: In a conversion device 1, a source of a FET 11 and a drain of a FET 12 are connected to one end of a coil L1, and a source of a FET 13 and a drain of a FET 14 are connected to the other end of the coil L1. Sources of the FETs 12, 14 are connected together. A cathode and an anode of a diode D3 are connected to a drain and the source of the FET 13, respectively. After a state where the FETs 11, 13 are off transitions to a state where the FET 11 can be turned on/off and the FET 13 is off, the FET 13 is kept off. In the meantime, the FETs 11, 12, 14 are individually turned on/off to generate output current flowing between the drain of the FET 13 and the source of the FET 14 via a storage battery 4. After the output current is generated, the FET 13 is released from the off condition. |
