Abstract

The invention discloses a dual-power redundant cold standby uninterrupted switching circuit. The dual-power redundant cold standby uninterrupted switching circuit comprises a detection and output control circuit, an MOS tube driving circuit and a fault detection and control signal feedback circuit, wherein the detection and output control circuit and the fault detection and control signal feedback circuit are connected to the MOS tube driving circuit respectively; and voltage input and output pass through the MOS tube driving circuit respectively. Compared with the prior art, the dual-power redundant cold standby uninterrupted switching circuit has the advantages that firstly, the circuit realizes industrial mainframe box power redundant backup, the design of a power redundant single board is realized, the switching circuit is realized on the single board, and the replacement of a faulted power module in an uninterrupted power condition of equipment is satisfied; and secondly, the circuit is constructed and formed by using common passive components and parts without special requirement, and the circuit is simple, reliable and low in environmental requirement.

Description

technical field [0001] The invention relates to the technical field of automation technology, and is especially used in a system requiring that the important equipment cannot be restarted during work, so as to realize the redundant backup function of the power supply. Background technique [0002] For long-term uninterrupted operation and highly reliable systems, such as base station communication equipment, vehicle equipment, servers, etc., a highly reliable power supply is often required. Redundant power supply design is a key part of it and plays an important role in high reliability systems. The redundant power supply is configured with 2 power supplies. When one power supply fails, the other power supplies can be switched on immediately without interrupting the normal operation of the equipment. This is similar to the working principle of UPS power supply: when the mains power is cut off, the battery will replace the power supply. The difference between redundant powe...
