Abstract:
A power converter includes: two DC input terminals that input a DC input voltage; two DC output terminals that output a DC output voltage; an isolation transformer with a primary winding and a secondary winding; a switch that is connected across the two DC input terminals in a state where the switch is connected in series to the primary winding and that switches the DC input voltage; an LC resonance circuit that includes an inductance and a capacitance and is connected in parallel to the primary winding; a first resonant capacitance that is connected in parallel to the switch; a second resonant capacitance that is connected in parallel to the secondary winding; and a rectifying and smoothing circuit that rectifies and smoothes a voltage generated across both ends of the second resonant capacitance and outputs as the DC output voltage across the two DC output terminals.

Claim (Index 11):
The power converter according to  claim 2 ,\n wherein frequency characteristics of an impedance when looking from both ends of the switch when the two DC input terminals are shorted are formed so as to include, in order from a low frequency band to a high frequency band, a first resonant frequency, a second resonant frequency, a third resonant frequency, a fourth resonant frequency, and a fifth resonant frequency, only the first resonant frequency and the second resonant frequency out of the five resonant frequencies are lower than a switching frequency of the switch, only the third resonant frequency is lower than a frequency that is double the switching frequency, the fourth resonant frequency is substantially equal to double the switching frequency, the fifth resonant frequency is higher than double the switching frequency, and the impedance has local maxima at the first resonant frequency, the third resonant frequency, and the fifth resonant frequency and has local minima at the second resonant frequency and the fourth resonant frequency.
