Abstract
A power conversion device including an alternating current (AC) source, a plurality of switching units connected in series between positive and negative terminals of the AC source, each including a semiconductor switching element and having a load connected thereto, each switching unit outputting, to the load connected thereto, an input current from the AC source and a direct current (DC) output voltage that is generated through ON/OFF control of the semiconductor switching elements, a capacitor connected in parallel with the AC source and with the switching units, an inductor inserted between the capacitor and the switching units, and between the AC source and the switching units, a current measurement unit that measures a value of a current flowing from the AC source to the capacitor, and a control device that performs the ON/OFF control on the semiconductor switching elements on the basis of the measured current value.
