摘　　要：中法海洋卫星载荷设备具有低频脉动负载特性,且地影期功率需求较大。为了防止载荷设备对其他设备产生干扰,电源控制器采用“内单外双”母线设计,简化了系统配置,减少体积和质量,降低研制成本。为降低电池组的放电深度,适应大电流放电需求,开发了国内单体容量最大的70 Ah航天用镉镍蓄电池。The payloads of CFOSAT have low frequency pulsating load characteristics and high power demand during the shadow period.To prevent the payloads from interfering other equipments of the satellite,the power control unit has been designed as a single internal and dual external bus.The design has the advantages of simplifying the system configuration,and reducing the size,weight and cost.In order to reduce the depth of discharge of the battery pack and adapt to the demand of high current discharge,the largest capacity of 70 Ah aerospace cadmium nickel battery in China has been developed.
