Title:
POWER SOURCE SWITCHING CIRCUIT AND POWER SOURCE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/253433
Kind Code:
A1
Abstract:
A power source switching circuit, applied to a power source apparatus. The power source apparatus comprises a first power source and a second power source, wherein the first power source is used for supplying power to a system; the second power source is a backup power source; the first power source and the second power source are used for supplying different voltage values, and the voltage value of the first power source is greater than the voltage value of the second power source; the power source switching circuit is electrically connected to the first power source and the second power source; when the first power source works normally, the power source switching circuit outputs a first voltage; and when the first power source is abnormal, the power source switching circuit outputs a second voltage, wherein the voltage value of the first voltage is less than the voltage value of the second voltage. Further provided is a power source apparatus comprising the power source switching circuit.
