| description | The present invention relates to a switch controller, a power supply including the same, and a driving method thereof. An AC input of the power supply is connected to a rectification circuit. The power supply includes a power switch to which the AC input passed through the rectification circuit flows during a turn-on period of the power switch and a switch controller detecting a half-on time point that is an intermediate time point of the turn-on period, calculating the AC current using a result of sampling a sense voltage that depends on a current flowing to the power switch during the turn-on period at the half-on time point and the turn-on period, and controlling the input current to have a reference sine wave. The reference sine wave has a sine wave that is full-wave rectified from the AC input. |
