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 1):
A power converter comprising:\n two direct current (DC) input terminals that are plus and minus and into which a DC voltage is inputted; two alternating current (AC) output terminals that output an AC voltage; a switch with two ends; a first resonant capacitance connected between both ends of the switch; a first LC resonance circuit that is connected in series together with the switch between the AC output terminals; and a second LC resonance circuit that is connected between the two DC input terminals and both ends of the switch, wherein the first LC resonance circuit includes a current path including a series circuit composed of an inductance and a capacitance, and when looking from both ends of the switch when the two DC input terminals are shorted, frequency characteristics of an impedance of the second LC resonance circuit include, in order from a low-frequency side to a high-frequency side, a first resonant frequency, a second resonant frequency, a third resonant frequency, and a fourth resonant frequency, the first resonant frequency is higher than a switching frequency of the switch, the second resonant frequency is a resonant frequency that is around double the switching frequency, the fourth resonant frequency is a resonant frequency that is around four times the switching frequency, and the impedance has local maxima at the first resonant frequency and the third resonant frequency and local minima at the second resonant frequency and the fourth resonant frequency.
