Abstract: A power conversion apparatus, which converts power of a DC power supply and provides it to a plurality of loadings, includes a transformer, an electronic switch, a leakage energy recycling circuit, and a plurality of output circuits. The transformer has a plurality of primary windings, which receives the power, and a plurality of secondary windings, which outputs the converted power. One end of the electronic switch is electrically connected to the primary windings; the other end thereof is electrically connected to the DC power supply. The leakage energy recycling circuit is electrically connected to the primary windings, and repeatedly and alternatively outputs the powers of positive and negative voltage. The circuit receives and stores leakage energy of the transformer, and feedbacks it to the transformer. The output circuits are electrically connected to the secondary windings to receive the converted power and to provide it to the loadings.
