Abstract: A power converter includes external connection terminals, bridge circuits, an inductance element and a controller. The bridge circuits are connected to the external connection terminals, respectively. The inductance element is connected between an AC terminal of one of two of the bridge circuits and an AC terminal of another one of two of the bridge circuits. The two of the bridge circuits are capable of transmitting power. A closed-loop circuit is formed by the two of the bridge circuits and the inductance element. The closed-loop circuit includes a capacitor connected between the inductance element and at least one of AC terminals of the two of the bridge circuit. The controller drives switching elements at a switching frequency being higher than a resonant frequency of the closed-loop circuit.
