Abstract: In a power converter, a plurality of resonant capacitors are provided one to one for a plurality of switches, respectively. Each of the plurality of resonant capacitors is connected between a first terminal of a corresponding one of the plurality of switches and a second DC terminal. A controller controls a plurality of first switching elements, a plurality of second switching elements, and the plurality of switches. When determining that two-phase resonant currents corresponding to two switching circuits belonging to a plurality of switching circuits flow simultaneously through a resonant inductor, the controller performs control of shifting respective ON periods of the first switching element and the second switching element in one switching circuit out of the two switching circuits.
