Abstract
A power conversion system includes a voltage detection circuit and a logic circuit. When the logic circuit determines that the drain-source voltage of the power switch is less than zero through the detecting terminal of the voltage detection circuit, the logic circuit outputs the first high-level voltage. Accordingly, the driving circuit outputs the second high-level voltage to the power switch according to the first high-level voltage. Consequently, the gate-source voltage of the power switch is pulled high. When the reverse current flows from the source to the drain of the power switch, the energy loss of the power switch due to the drain-source voltage of the power switch in power conversion system operated at high frequency is reduced.
