Design and research on a power distribution system for airborne radar

Abstract

With the rapid progress of electronic and computer technology, as well as the application requirements under complicated conditions, modern airborne radars are developing to multifunction, highly integrated, digital and modular. As a ‘heart’ component of the radar, the performance and reliability of the distribution system is one of the decisive factors for its development. In this work, the design and research of an airborne radar power distribution system was introduced. The distribution system adopts the layered and fused power supply architecture of ‘centralized rectification, decentralized voltage stabilization’. Further, according to the actual application requirements, the input under-voltage and over-voltage protection, health management and other functional modules were added. The detailed composition, design and the corresponding implementation scheme of the distribution system were carefully investigated. The test results show that the system is controllable, stable and reliable, and the performance index meets the requirements of the radar system for the power supply characteristics. The distribution system is feasible, and has important reference significance for the design of power supply and distribution system of other radars.
