POWER DEVICE AND POWER SUPPLY METHOD

摘要

Disclosed are a power supply device and a power supply method thereof. The power supply device comprises; a pulse width modulation unit which modulates and outputs power; a control unit which sets a dead time according to a control time; and a dual FET unit which receives the power by being turned on-off according to the dead time. The power supply device and the power supply method of the present invention suppress a distortion factor of an output end maximally and prevent shoot through by controlling a dead time.
