power bus circuit

Abstract

The present invention is applicable to the high-voltage power supply field, and provides a power supply bus circuit. The power supply bus circuit includes a high-voltage power supply circuit, the high-voltage power supply circuit includes at least two first alternating current / direct current conversion modules and further includes at least two high-voltage direct current power supply buses, and the first alternating current / direct current conversion module connects to mains, adjusts the connected mains into a high-voltage direct current, and outputs the high-voltage direct current to a high-voltage direct current power supply bus that is electrically connected to the first alternating current / direct current conversion module, where the high-voltage power supply circuit further includes at least one first direct current / direct current conversion module, where the first direct current / direct current conversion module performs voltage conversion on a high-voltage direct current between two high-voltage direct current power supply buses connected to the first direct current / direct current conversion module, so as to implement mutual backup of power supplies between the two high-voltage direct current power supply buses, and ensure that, in a case in which one of the high-voltage power supply buses does not become off, the two high-voltage power supply buses that are mutually backed up may power loads on the high-voltage direct current power supply buses without interruption.

Description

technical field [0001] The invention belongs to the field of high-voltage power supply, in particular to a power supply bus circuit. Background technique [0002] With the continuous innovation and rapid changes of the information technology industry (Information technology, IT), communication technology industry (Communication technology, CT) and information and communications technology (Information and Communications Technology, ICT), higher requirements are put forward for data bearing equipment. If it is required that the data bearing equipment cannot be powered off. [0003] In particular, servers and storage devices as data bearing devices require stable and continuous uninterrupted power supply. In the prior art, the industry's power supply for data bearing equipment has the following three characteristics: 1) Multiple redundant power supplies are designed, and the redundant power supplies are all mounted on a single bus, thereby ensuring that the single bus is effe...
