Abstract
An AC/DC converter includes: a charge accumulation unit including first and second capacitors connected in series; a switching unit including a switch unit; a control unit; a switch drive unit; and first current and second current detection units. The switch unit includes first and second switching elements connected in series. The switching unit switches between charging and non-charging of each of the first and second capacitors. The switch drive unit causes the first and second switching elements to perform an ON/OFF operation exclusively to each other. A current detector of the first current detection unit is disposed between a rectifier circuit and the switch unit. The control unit detects a current flowing through the switch unit on the basis of based on a difference value between a detection value of a first current detected by the first current detection unit and a detection value of a second current detected by the second current detection unit.
