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.

Abstract: A power supply system with current sharing includes a current sharing bus, a plurality of power supply units, and a plurality of controllers. The power supply units are connected to each other through the current sharing bus. Each power supply unit provides a current sharing signal value to the current sharing bus, and provides an output current to a load. Each controller receives current sharing signal values provided from other power supply units and current signal values corresponding to the output currents. When determining that the current signal value is less than a reference current sharing signal value, the controller increases an output voltage of the power supply unit to increase the output current. Otherwise, the controller decreases the output voltage to decrease the output current so that so that the output currents of the power supply units are shared to supply power to the load.
