Abstract
The present invention provides a power supply apparatus for outputting an output voltage according to a first signal from outside, the power supply apparatuses comprises a rectifier, a power transformer, a power control circuit, and a switching device. The rectifier is provided for supplying a DC voltage source. The power transformer receives the DC voltage source, then outputs the output voltage and a second signal. The power control circuit is provided for controlling the output voltage of the power transformer according to the second signal, then the switching device outputs the second signal to the power control circuit according to the first signal.
