Abstract
The present invention relates to a power supply to provide power output with stable process control. The DC output terminal of power supply has a transformer, the secondary side of the transformer is connected to a clamping circuit. Since the clamping circuit is installed on the secondary side of the buck transformer, it is not necessary to sustain the high DC-voltage to drive the clamping circuit for actuation. Also, the clamping circuit can clamp the high voltage sustained by the drain when the MOSFET is OFF, so that the high-voltage sustained by the MOSFET is reduced, so as to increase the reliability of the MOSFET. Furthermore, the transformer can release or eliminate the energy generated due to magnetic leakage and inductance, and stored in the transformer, thereby the transformer is prevented from saturation.
