Through the research of CPCI hot plug and avionics data bus ARINC429, this paper analyzes and proposes the improvement direction needed to support the high availability hot plug for ARINC429 in CPCI. In addition, this paper also designed the high availability hot plug ARINC429-CPCI board in practice, and provided the necessary support from hardware and software to achieve the target functions.

Bidirectional DC-DC converters are widely used in many fields, but generally the charge methods of the step-down circuitin these converters have not been gained enough attention. Based on the characteristics of the bidirectional flow of energy, this paper proposes PPNT (Pre charge - Positive and Negative pulse charge - Trickle charge)charge method. Theoretical model is established, and its feasibi...Show More
