Abstract

The invention discloses a redundant direct-current power supply system. The system is characterized in that an anode of a first power output end is connected with the anode of a first diode to form afirst power subsystem; the anode of a second power output end is connected with the anode of a second diode to form a second power subsystem; cathodes of two diodes are connected so as to be served asthe anode of the output end of a redundant direct-current power supply system; and the cathode of the first power output end is connected with the cathode of the second power output end so as to be served as an output end cathode of the redundant direct-current power supply system. Two power supply control subsystems are a main power supply control subsystem and a standby power supply control subsystem so as to guarantee an uninterrupted power supply state of the system, reliability of the system is improved, and simultaneously, a mutual coupling phenomenon caused by direct parallel connection of the two power supplies is avoided, and then damages of components are prevented.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of electronic circuits, in particular to a redundant DC power supply system. Background technique [0002] Communication, navigation, medical equipment and industrial automation systems generally do not allow power supply interruption, and their reliability requirements are very high. The use of power redundancy is the main measure to improve system reliability. In the prior art, two DC power supplies are directly connected in parallel and powered on to supply power to the load at the same time. If one of the power supplies fails and stops supplying power, the other power supply can also provide power supply protection, thereby avoiding the failure of the entire system. [0003] But technically speaking, the outputs of two power supplies cannot be directly connected in parallel. This is because the general DC power supply is a closed loop system with voltage control. In the case where the...
