The VPX power standard is currently the most compatible military embedded computer standard internationally， and its modules can stably power multiple different functional modules in the chassis. A VPX power board based on VITA46 and VITA62 standards was designed. The design architecture， ideas， and functions of the 6U structure power supply board were mainly introduced. The circuit characteristics of hardware protection， slow start， acquisition， and DCDC module power supply were analyzed. The software working mode， management process， and external structure design were described. Maxwell thermal simulation was used to analyze the working status of the board in high temperature environments. Finally， the stability and reliability of the board's power on timing were tested through experiments， and load stability and voltage stability under load. Through the research and development of software and hardware， the proposed design has accumulated some experience in terms of autonomous hardware design， software adaptation， and other aspects.
