According to one embodiment, a power conversion device (1) includes a DC conversion circuit (12), an output conversion circuit (13), and a control circuit (15). The DC conversion circuit (12) converts an external power supply voltage (E) to a DC voltage (VDC). The output conversion circuit (13) includes a switching element (Q2) which converts a DC voltage (VDC) which is converted in the DC conversion circuit to an output voltage (V0) corresponding to a load (11), and supplies the output voltage to the load. The control circuit (15) controls an ON time of the switching element (Q2) to be constant, regardless of a value of the output voltage (V0) corresponding to the load, which is output from the output conversion circuit. |
