POWER SUPPLYING APPARATUS

摘要

The present invention relates to a power supplying apparatus of a phase shift full bridge (PSFB) method for controlling the switching of a leading leg switch and a lagging leg switch according to a point of time at which a direction of a primary side current changes. The apparatus comprises: a power supply unit which supplies a predetermined direct current (DC) power by switching an input power through a phase shift full bridge method; a detection unit which detects a signal waveform of a primary side current generated when switching the power of the power supply unit; and a control unit which synchronizes a point of time at which a direction of the primary side current changes with a switching operation of the power supply unit according to the signal waveform of the primary side current detected from the detection unit.
