Abstract: A power supply apparatus including a master power converter and a slave power converter is provided. The master power converter generates a main power having a working voltage level. The slave power converter generates an auxiliary power. According to its operation state, the master power converter provides a corresponding control signal to the slave power converter. If the master power converter determines the operation state is a first operation state, the slave power converter generates the auxiliary power having a voltage level lower than the working voltage level, so that the slave power converter can be operated in a no-load conversion state. If the master power converter determines the operation state is a second operation state, the slave power converter raises the voltage level of the auxiliary power to the working voltage level, so that the auxiliary power replacing the main power is supplied to a load.
