摘　　要：随着雷达向着小型化方向的发展,如何在苛刻环境下实现阵面电源的轻量化、小型化和高稳定性设计面临巨大挑战。文中针对某车载相控阵雷达用阵面电源,提出了全新的设计思路来实现阵面电源的小型化设计。首先进行详细的结构和热设计,利用模块化设计和三维布局设计实现尺寸和重量要求;在此基础上利用有限元分析软件进行仿真分析以验证设计的合理性;最后进行设计改进来优化电源性能。结果表明,在实现电源尺寸缩小50%,重量减少30%而功率密度增大近1倍的情况下,热设计和结构设计满足使用要求。采用此设计理念可有效降低设计差错,缩短研发时间。With the development of miniaturization for radar, the design of array power supply with light mass, small size and high stability in harsh environment faces great challenge. In this paper, the new design concept for the array power supply of a vehicle-borne radar is proposed to realize the miniaturization design. Firstly, the detailed structure and thermal design are carried out, the methods of modular design and three-dimensional layout design are used to realize the size and weight requirements. To verify the rationality of the design, simulation results by finite elements analysis software are presented. At last, the design is improved to optimize the performance of the power supply. Results indicate that the array power supply reduces its size by 50% and its weight by 30% while its power density is almost doubled, at the same time, its structure and thermal design satisfy the application requirements. The design errors and development time are effectively reduced by adopting this design concept.
