为了满足实验类空间仪器对空间电源系统的低成本、高集成度、微型化的需求，设计了以C8051F040芯片为控制核心的空间仪器电源控制器。该控制器与传统设计方式的最大区别是采用高集成度的锂离子电池控制芯片(bq77PL900)代替了原有的模拟电路。通过使用该芯片不仅大大降低了控制器所占体积，减小了控制器的功耗，而且提高了控制器的抗干扰能力。为了提高系统的可靠性，该系统还采用在线EEPROM充注技术，可以及时发现控制器内部被打翻的数据并进行恢复。通过实验证明该设计简单可靠，而且能量转换效率也提高了5%左右。该设计可广泛应用于低成本的空间仪器的电源、微小型卫星的电源系统。

In order to meet the needs of low-cost, high integration space instruments for space power systems, a space-based instrument C8051F040 chip power controller was designed. The major difference between the controller and the traditional design approach is the use of highly integrated lithium-ion battery controller chip (bq77PL900) as an integrated controller chip instead of analog circuits. By employing the bq77PL900, the size of power controller is reduced and the energy of the power controller used is decreased, and the anti-jamming ability of the system is enhanced. To improve the reliability of the system, the system uses the online EEPROM re-injection technology, which can be used to discover the knocked data. This experiment proves that this design not only greatly simple and reliable, but also enhance the efficiency of the system by 5%. This design can wildly used in low-cost space instruments and small satellites.
