Design and Power Supply‘s Quality Analysis of the Automatic Power Distribution System Based on SSPC

Abstract

In complex and severe electromagnetic environment with more electric aircraft (MEA) and aircraft missions diversity, the power supply quality analysis and its corresponding circuit design is a key technology for the design of automatic power distribution system on airborne platform. By analyzing the structure and the characteristics of automatic power distribution system and its executive component – SSPC, this paper improves the power supply quality through paralleling RC circuit to MOSFET to absorb current shock and voltage fluctuation,and gives the calculating method of the RC components. By experiments with principle prototype, it is verified that the method can reduce the dynamic voltage fluctuation of the power supply system.
