The present invention relates to a power supply device and a power supply device for lighting, capable of resolving an imbalance in power between a resonance type inverter and a driving circuit by forming an inductance of a direct current converting circuit connected to a rear end of an LCC resonance type inverter and an LLCC resonance tank. The power supply device comprises: an inverter to convert input power to the predetermined alternating current power in an inductor-inductor-capacitor-capacitor (LLCC) resonating manner; and a converter which includes a transformer having an inductance to form the inverter and an LLCC resonance tank, rectifies the alternating current power received from the inverter through the transformer, and switches the rectified power to be converted to direct current power. |
