POWER SUPPLYING APPARATUS
First Claim
1. A power supplying apparatus comprising:
- a power supply unit switching input power to convert the input power into preset direct current (DC) power;
a detecting unit setting a reference voltage based on the DC power of the power supply unit and comparing the reference voltage with a ripple voltage included in the DC power to detect a voltage level of the ripple voltage; and
a controlling unit determining whether an abnormality has occurred according to a detection result of the detecting unit.

Abstract
There is provided a power supplying apparatus capable of determining whether to be normally operated by detecting whether a capacitor deteriorates with age based on a ripple voltage generated by switching of a primary side, the power supplying apparatus including a power supply unit switching input power to convert the input power into preset direct current (DC) power, a detecting unit setting a reference voltage based on the DC power of the power supply unit and comparing the reference voltage with a ripple voltage included in the DC power to detect a voltage level of the ripple voltage, and a controlling unit determining whether an abnormality has occurred according to a detection result of the detecting unit.
