Abstract: Technical standard and technique characteristics of VPX bus were introduced. The composition and function of power supply and distribution system using VPX bus were presented. And then, based on VPX bus architecture, the power supply, control and instruction of VPX board was analyzed, and the technical proposal was finished. Some experiments which optimized board configure were carried out, and the result proved that the power supply and distribution system using VPX bus architecture has a superior stability. Then the system had applied foreground.

Key words: VPX bus, Power supply and distribution system, Intelligence
