Embodiment Construction

[0017] see figure 1 The intelligent distributed power system consists of a primary power conversion module (PCM), a switch array (PSA), a power management module (PMS), several secondary power conversion components (PCE) placed on the computer electronic module (LRM) and multiple It consists of a voltage regulator module (VRM).

[0018] The primary power conversion module (PCM) adopts a standard LRM structure (length 233mm, width 160mm, thickness 50mm), and is distributed on the computer integrated rack.

[0019] The secondary power component (PCE) adopts a non-standard component structure and is distributed on the computer electronic module (LRM).

[0020] The voltage regulation module (VRM) uses a non-standard module structure and is distributed next to the load (IC) on the LRM.

[0021] The 270V high-voltage DC is converted by the power conversion module (PCM) to output a stable 48V DC voltage, which is controlled by the PSA to provide redundant power supply to the LRM mo...

Abstract

The invention provides an onboard computer power system which comprises a power conversion module, a switch array, a power management module and computer electronic modules, wherein secondary power conversion assemblies and a plurality of voltage adjusting assemblies are arranged on the computer electronic modules; the power conversion module is a power conversion unit which is arranged on an integrated stand to realize power conversion of high voltage input into stable middle busbar voltage of 48V, the power conversion module is connected with the secondary conversion assemblies on the computer electronic modules through the switch array to supply power for the computer electronic modules; and the computer electronic modules are converted into direct current voltage of 5V through the secondary power conversion assemblies, and supply power for a load through the voltage adjusting assemblies near loads on the computer electronic modules. The invention solves the technical problem of poor reliability of the traditional power supply, and has the advantages of high reliability, easy maintenance, and the like.

Description

technical field [0001] The invention relates to the field of computers, in particular to an airborne computer power supply system. Background technique [0002] At present, the computer in the avionics system is highly integrated, and the on-board electronic equipment continues to increase, requiring a more efficient and reliable power supply system that can achieve intelligent management. This project has not yet been carried out by domestic airborne product factories, and the new generation of foreign aircraft avionics integrated processors has adopted this technology. With the change of the power supply mode of fighter jets and the improvement of the high degree of integration of airborne equipment, high-density and high-reliability power supply systems will become a key part of the application of integrated core processors, and distributed power supply systems will emerge as the times require. It has output power Scalability, flexible design, high reliability, standardi...
