Current regulation apparatus

摘要

A current regulation apparatus is provided. The current regulation apparatus includes a trans unit, a first switching unit, a voltage detection unit, a voltage comparison unit, and a control unit. The trans unit includes an auxiliary winding unit. The first switching unit controls an operation of the trans unit. The voltage detection unit detects a voltage induced to the auxiliary winding unit. The voltage comparison unit compares a voltage detected by the voltage detection unit and a reference voltage. The control unit adjusts a turn-on section of the first switching unit according to an output voltage of the voltage comparison unit.
