Abstract: A parallel resonant converter circuit with current-equalization function includes a power input terminal, a power output terminal, an output capacitor, first and second resonant converters and a third transformer. The first resonant converter is electrically coupled between the power input terminal and the output capacitor/power output terminal. The first resonant converter includes a first transformer. The second resonant converter is electrically coupled between the power input terminal and the output capacitor. The first resonant converter and the second resonant converter are coupled in parallel. The second resonant converter includes a second transformer. The third transformer includes a first coil winding set and a second coil winding set. The first coil winding set is electrically coupled between the power input terminal and the first transformer in series. The second coil winding set is electrically coupled between the power input terminal and the second transformer in series.
