Abstract
A power supplying apparatus may be capable of switching off a synchronous rectifier on a secondary side in advance by predicting a switching-on time on a primary side. The power supplying apparatus may include: a power converting unit switching power input to the primary side and transferring the power to the secondary side; and a synchronous rectifying unit formed on the secondary side, synchronized with the switching of the power converting unit to perform a rectification switching operation, thereby rectifying the power transferred from the power converting unit, and changing the rectification switching operation before a switching change point of the power converting unit depending on a preset timing.
