PURPOSE: An LLC resonant converter is provided to simplify the circuit of a power source device by outputting a plurality of voltages using one resonant part, thereby reducing manufacturing costs of the power source device. CONSTITUTION: First and second switching parts(110,120) are serially connected between two electrodes of DC power supply(10). The first and the second switching part are composed of an MOSFET(Metal-Oxide-Semiconductor Field Effect Transistor). A resonant part(130) executes LLC resonance using a resonance inductor(132) and a resonating capacitor(134) according to a switching operation of the first and the second switching part. A first output part(140) outputs first voltage by inducing voltage which is applied to the primary wiring of a first transformer(142) to a secondary winding according to a resonant operation of the resonant part. The first output part outputs the first voltage by including a first rectification flattening part. |
