Embodiment Construction

[0027] The core idea of ​​the single-board power supply system of the present invention is: divide the single-board into core and non-core two planes, and introduce backup power to supply power to the core part power plane and the non-core part power plane respectively, thereby ensuring the non-core part power supply When there is a device short circuit on the plane, it can still provide reliable power supply to the core part of the power plane to ensure the normal and stable operation of the system. Specific embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0028] Please refer to FIG. 2, which is a system block diagram of the single-board power supply system of the present invention, and the single-board power supply system includes:

[0029] single board, the single board is divided into a core part power plane and a non-core part power plane, wherein, the core parts on the power plane are all core devices, and if...

Abstract

The disclosed system comprises single board, main power supply setup at the single board in use for supplying power for the single board, and back up power supply. The single board is divided into core part of power supply plane and non - core part of power supply plane. The said back up power supply provides respective back up power supply for the said core part of power supply plane and non - core part of power supply plane independently. Comparing prior arrangement, the invented system will not occur power down for whole single board if short circuit of a device in non - core part of power supply plane happens.

Description

technical field [0001] The invention relates to power supply technology in the field of electronics or communication, and specifically refers to a single-board power supply system. Background technique [0002] In some products with very high reliability requirements, the power supply requirements for important boards are very high, and the power supply of some circuits on the board is not allowed to be affected or interrupted, otherwise the normal operation of the system will be affected. It can be seen that how to ensure the reliable power supply of the single board has become a key technology to improve product reliability. [0003] In order to ensure reliable power supply of the board, the following two power supply schemes are commonly used in the prior art: [0004] The first one is to improve the reliability of the single board power supply by selecting a high-reliability dedicated power supply device. For example, military-grade power devices are used in commercial...
