Abstract
The power supply includes: an electromagnetic interference filter including a first filter which has a pair of electromagnetically coupled cores having at least two leg parts, first and second bobbins each having a tube-shaped body part having a penetration hole into which each of the leg parts is inserted and having a winding region defined as the circumference of the outer peripheral surface of the body part, and first and second coils respectively wound around the first and second bobbins to remove common mode electromagnetic interference included in power transmitted from a power line, the electromagnetic interference filter removing differential mode electromagnetic interference due to leakage inductance formed due to the leakage of magnetic flux flowing through the cores; a power factor corrector correcting a power factor of the power where the electromagnetic interference is removed; and a power converter switching the power-factor-corrected power into a driving power having a predetermined voltage level.
