A push-pull inverter allows a power supply unit to supply an input voltage to two primary windings of a transformer, and allows MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) to drive the transformer in push-pull mode so as to increase the input voltage supplied from the power supply unit and to output the increased voltage as an output voltage from a secondary winding of the transformer. The two primary windings of the transformer are mixedly wound on a same bobbin without being separated, so that when the transformer is driven, the two primary windings of the transformer are prevented from resonating with each other. This makes it possible to prevent turbulence in the input current, thereby reducing loss (power loss) of the MOSFETs, allowing the transformer to have a high efficiency.
