<p>PROBLEM TO BE SOLVED: To provide a power conversion device that allows accurately detecting a current and a voltage without being affected by noise.SOLUTION: A power conversion device 1 includes: an input section 10 to which an AC voltage is inputted; an output section 11 outputting an output voltage; a voltage conversion circuit having switching elements 14a and 14b, an inductor 12, a capacitor 13, and a control unit 17, and converting an input voltage into an output voltage; a voltage detection unit 18 detecting at least one of the input voltage and the output voltage; and a current detection unit 19 detecting a current flowing through the voltage conversion circuit. The control unit 17 controls operation of the switching elements 14a and 14b according to detection values obtained from the voltage detection unit 18 and the current detection unit 19. The voltage detection unit 18 changes the detection timing according to the period length of an ON state of the switching elements 14a and 14b.</p> |
