Abstract:
A power converter includes: input terminals for inputting a DC voltage; output terminals for outputting an AC voltage; a switch; a first resonant capacitance connected between both ends of the switch; a first LC resonance circuit connected in series with the switch between the output terminals; and a second LC resonance circuit connected between the input terminals and the switch. The first LC resonance circuit includes an inductance and a capacitance in series. When the input terminals are shorted, frequency characteristics of an impedance of the second LC resonance circuit include first to fourth resonant frequencies. The first resonant frequency is higher than a switching frequency of the switch. The second and fourth resonant frequencies are around double and four times the switching frequency. The impedance has local maxima at the first and third resonant frequencies and local minima at the second and fourth resonant frequencies.

Claim (Index 4):
The power converter according to  claim 1 ,\n wherein the second LC resonance circuit internally includes a seventh inductance, an eighth inductance, a ninth inductance, a fifth capacitance, and a sixth capacitance, the seventh inductance, the fifth capacitance, and the eighth inductance are connected in order in series between one DC input terminal out of the two DC input terminals and one end out of the two ends of the switch, another DC input terminal out of the two DC input terminals is directly connected to another end out of the two ends of the switch, the ninth inductance is connected in parallel to a series circuit composed of the seventh inductance and the fifth capacitance, and the sixth capacitance is connected between a junction between the seventh inductance and the fifth capacitance and the other end of the switch.
