Abstract: A power conversion apparatus and control method thereof are provided. The power conversion apparatus includes an output capacitor, an AC-to-DC conversion circuit, a transformer-based auxiliary circuit, an inrush suppression component and a switching circuit. The AC-to-DC conversion circuit is configured to convert an AC power into a DC power. The auxiliary circuit provides a leakage inductance energy. The inrush suppression component provides a first conduction path, and the switching circuit provides a second conduction path. When the switching circuit cuts off the second conduction path in response to the leakage inductance energy, the AC-to-DC conversion circuit conducts the DC power to the output capacitor via the first conduction path. When the switching circuit turns on the second conduction path in response to the leakage inductance energy, the AC-to-DC conversion circuit conducts the DC power to the output capacitor via the second conduction path.

Abstract: A forward-based power conversion apparatus is provided. When the forward-based power conversion apparatus supplies a plurality of (at least two of) output voltages to a load, a reverse voltage, corresponding to a lower output voltage, of a secondary winding of a transformer is captured through an equipped output auxiliary unit, so as to assist an output of a higher output voltage. Accordingly, compared to that described in the related art, the reverse voltage of the secondary winding of the transformer described herein can be converted into an effective power output, so that overall power loss of the power conversion apparatus can be reduced, and conversion efficiency of the power conversion apparatus can be improved.
