Abstract: A power supply system includes at least a first power supply and a second power supply and a voltage output circuit. The first power supply provides a first set of signals while the second power supply provides a second set of signals. The voltage output circuit includes a first input terminal, a second input terminal, a first output terminal, a switch circuit and a control circuit. The first input terminal receives a first voltage signal of the first set of signals while the second input terminal receives a second voltage signal of the second set of signals, the switching circuit couples between the first and the second input terminal and the first output terminal, and the control circuit activates a first or second transistor according to a voltage difference between the first and second input terminal to generate a first output voltage signal on the first output terminal.

Abstract: A power supply apparatus is provided. The provided power supply apparatus has a power backup mechanism, in which a main DC power and a backup DC power are switched by a fast switching circuit composed of a plurality of switch transistors. Since the switching time of each switch transistor is substantially shorter than that of the conventional relay, the backup DC power can be conducted to the input of the multi-output DC-DC converter at a quite-short time even though the main DC power is abnormal. Accordingly, the output of the multi-output DC-DC converter still can continuously and stably supply the operation power required by the load.
Abstract translation: 提供电源装置。 所提供的电源装置具有电力备用机构，其中通过由多个开关晶体管组成的快速开关电路来切换主DC电力和备用DC电力。 由于每个开关晶体管的开关时间明显短于传统继电器的切换时间，因此即使主直流电源为直流电源，备用直流电源也可以在相当短的时间内传导到多输出DC-DC转换器的输入端 不正常。 因此，多输出DC-DC转换器的输出能够连续稳定地供给负载所需的动作功率。
