Abstract
A DC/DC conversion apparatus includes a DC voltage source, an oscillation circuit being electrically connected to the DC voltage source, a plurality of switch elements, a switch controller, which closes or opens electrical connection between the DC voltage source and the oscillation circuit by switching turn-on and turn-off of the plurality of switch elements, and switches a direction of a voltage applied on the oscillation circuit between a first direction and a second direction, a transformation circuit, a detector to detect one or more parameter values of an input voltage and input current of the DC voltage source and an output voltage and output current to the transformation circuit, wherein when the parameter values vary, the switch controller adjusts a length of time in which the voltage applied on the oscillation circuit is in one of the first direction and the second direction, such that the output voltage and/or output current returns to an initial value.
