Abstract
A LC resonant converter using a phase shift switching method includes: a switching unit configured to receive a switching signal according to a phase shift control and to perform zero voltage switching (ZVS) in a leading leg circuit and a lagging leg circuit when a light load is present; a transformer configured to output an output voltage of the switching unit as a predetermined level of voltage; a resonance circuit unit configured to convert frequency characteristics of an alternating voltage transferred from the transformer; and a bridge rectifying circuit unit configured to rectify the alternating voltage whose frequency characteristics are converted into a direct voltage.
