Claim:
1. A power conversion device, comprising: a first circuit wherein a first inductor and a first bidirectional switching element are directly connected; a second circuit, connected in parallel to the first bidirectional switching element, wherein a second bidirectional switching element and a capacitor are connected; a serial switching element wherein 2N (N being a positive integer) switching elements, in each of which a diode is connected in anti-parallel, are connected in series; a serial storage element including first and second storage elements connected in series, the serial storage element being connected in parallel to the serial switching element; a first serial rectifier element, connected in parallel to the serial storage element, wherein first and second rectifier elements are connected in series; and a second inductor directly connected from an intermediate point of the 2N switching elements to a connection point of the second bidirectional switching element and the capacitor, wherein a connection point of the first and second storage elements is directly connected to a connection point of the first bidirectional switching element and the capacitor, a connection point of the first and second rectifier elements is directly connected to a connection point of the first bidirectional switching element and second bidirectional switching element, and alternating current applied to the first circuit is converted, and output from both ends of the capacitor.
