Patent attributes
A DC/DC conversion apparatus includes a DC voltage source that outputs a DC power supply voltage, an oscillation circuit electrically connected to the DC voltage source, switch elements, a switch controller that connects or disconnects electrical connection between the DC voltage source and the oscillation circuit by switching turn-on and turn-off of the switch elements, and switches a direction of a voltage applied to the oscillation circuit between a first direction and a second direction, and a transformation circuit that outputs a current generated in the oscillation circuit and converts the current into a DC current. The switch controller disconnects the electrical connection between the oscillation circuit and the DC voltage source before the direction of the voltage applied to the oscillation circuit is switched from the first direction to the second direction, and connects the electrical connection between the oscillation circuit and the DC voltage source and switches the direction of the voltage applied to the oscillation circuit to the second direction after a current flowing through the oscillation circuit has been outputted to the transformation circuit.
