Abstract

The invention belongs to the field of power supplies, and provides a CPCI (compact peripheral component interconnect) power unit and system. The power unit comprises a main power switching module, a battery pack, a battery charging and power distributing circuit, a power supply switching circuit, and a power management circuit. In the invention, a power switching circuit and a battery power supply circuit are integrated in the CPCI power unit, the power switching circuit controls to use a main power supply or a battery to supply power to a system based on the state of the main power supply and the battery pack so that the CPCI system is miniaturized and has good stability and portability, and the overall CPCI system has good mobility by a built-in battery power supply system.

Description

technical field [0001] The invention belongs to the field of power supplies, in particular to a CPCI power supply device and system. Background technique [0002] With the development of society, computers play an important role in all walks of life. Many industries such as telecommunications, network, industrial control, military, aerospace, water conservancy, transportation, surveying and mapping, and medical treatment have extremely high reliability requirements for computers. . Compact PCI (Compact Peripheral Component Interconnect, CPCI) is a high-performance industrial bus based on the PCI electrical specification. Mainly through improvements in structure and electrical aspects, the entire system has achieved high reliability far higher than that of ordinary computers. [0003] In order to ensure the stable operation of the entire CPCI system, a stable power supply system is essential. The CPCI system mainly realizes stable and reliable power supply through redundant...
