Abstract:

The stability of the airborne equipment relies on the safe and reliable power supply system.In this paper,a power system with automatic monitoring and protecting function is studied,and the intelligent power module's hardware and software implementation method is discussed in detail.Based on DSP processor SMJ320F240,power module structure of 1+1 redundant power supply is adopted,which can realize the current voltage detection,input overvoltage surge suppression,input peak surge suppression and other intelligent management functions.

Key words: intelligent power;DSP;intelligent management
