Abstract

An embodiment of the present invention provides a circuit for realizing redundancy of a non-redundant power supply, which is used to solve the technical problem that the non-redundant ATX power supply cannot be used in systems requiring redundant functions in the prior art. The embodiment of the present invention includes: at least two isolation circuits and output terminals; the isolation circuit includes: a control chip with an ORING function, MOS transistors with the same number as the control chips, and input terminals with the same number as the control chips. In the embodiment of the present invention, the control chip with the ORING function controls to turn off or turn on the same number of MOS transistors as the control chip, thereby realizing the redundancy of more than two power supplies.

Description

technical field [0001] The invention relates to the field of redundant power supplies, in particular to a circuit for realizing redundancy of non-redundant power supplies. Background technique [0002] The function of the ATX power supply is to convert the AC 220V power supply to the DC 5V, 12V, 24V power supply used inside the computer. Compared with AT power supply, ATX power supply adds "+3.3V, +5VSB, PS-ON. [0003] Isolation redundancy means that one or more UPSs are used as the first-level power protection equipment, and another machine is used as the second-level power supply for backup. The primary power supply has its own load bus, and the secondary power supply provides bypass power for all primary power supply devices. When working, the secondary power supply runs without load, but it is required to bear the load from 0% to 100% within a cycle time. When the primary power supply is switched from mains mode to bypass mode, the transfer switch automatically disco...
