摘　　要：分析了传统的集中式电源架构(CPA)存在的问题,根据新型机载计算机的特点,提出了一种两级电源转换架构。通过研究分布式电源架构(DPA)和中间总线架构(IBA),解决了原有的CPA存在线压降大、分布参数对快速动态负载响应的影响等问题,不仅实现了大功率电源系统高效率转换、低压大电流负载点转换,进而提高了计算机系统的性能和可靠性。最后,建立了实验模型并给出了实验结果。The paper analyzes some existing problems of traditional Centralized Power Architecture （CAP）. Based on characteristics of next generation airborne computers, a two-level power converter architecture is proposed. The load transient response influenced by higher voltage drop and distributed parameters aresolved with Distributed Power Architecture （DPA） and Intermediate Bus Architecture （IBA）. Higher efficiency of higher power conversion can be implemented with DPA and point -of-load （POL） of lower-voltage higher current can be implemented with IBA. , so that performance and reliability of the computers can be improved. Final, the paper gives experimental prototypes and results in order to validate IBA.
