针对航空二次电源要求效率高、体积小、重量轻、高可靠性及实时性强的特点,研制了以F2812芯片为核心的嵌入式数字控制保护器,使DC/DC变换器实现自检测、健康预测和性能监控以及保护等功能。该保护器通过RS485总线与上位机进行信息交流,并将必要信息存储,同时阐述了试验过程中暴露的主要问题和解决措施,该保护器具有良好的工程应用价值。
Aiming at the characteristics of high efficiency, small size, light weight, high reliability and real-time performance of aviation secondary power supply, an embedded digital control protector with F2812 chip as the core is developed to realize self-testing of DC / DC converter, Health prediction and performance monitoring and protection functions. The protector communicates with the host computer through the RS485 bus and stores the necessary information. At the same time, it expounds the main problems exposed during the test and their solutions. The protector has good engineering application value.
