Abstract: A power supply apparatus is provided. The power supply apparatus includes two power suppliers connected in parallel, and the two power suppliers supply electric power to an electronic product at the same time. According to the present invention, when a load is a light load, the conductive impedance of an output isolation switch-component (for example, a metal-oxide-semiconductor field-effect transistor (MOSFET)) in each power supplier is changed/adjusted to balance the voltages on two light-loading setting points (not the source or drain of the output isolation switch-component (MOSFET)). If the voltages on the two light-loading setting points are not balanced (i.e., a reverse current is about to flow into the power supplier), the output isolation switch-component (MOSFET) is turned off in advance, so that a power isolation function is started/activated before the reverse current flows into the power supplier.
