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.
