Abstract
According to one embodiment, a power conversion device includes a DC conversion circuit, an output conversion circuit, and a control circuit. The DC conversion circuit converts an external power supply voltage to a DC voltage. The output conversion circuit includes a switching element which converts a DC voltage which is converted in the DC conversion circuit to an output voltage corresponding to a load, and supplies the output voltage to the load. The control circuit controls an ON time of the switching element to be constant, regardless of a value of the output voltage corresponding to the load, which is output from the output conversion circuit.
