面向大型无人机的一种高频大功率模块电源设计

Design of a High Frequency and High Power Module Power Supply for Large UAV

大型无人机采用发动机驱动,通过发电机和电源变换器的组合方式为整个飞机供电。与小型无人机常规供电电池不同,高频大功率模块电源具有功率容量大、寿命长且无需维护等优点。通过深入分析高频大功率模块电源的工作原理,详细设计电路参数,研制出一台200~400 V直流输入、28 V直流输出且额定功率为1 kW的模块电源样机,测试结果验证了理论设计的正确性。

Large UAV is driven by engine and is powered by generator and power converter.Different from the conventional battery power supply of small UAV,high frequency and high power module power supply has the advantages of large power capacity,long life and no maintenance.Through the in-depth analysis of the working principle of high frequency and high power module power supply,the circuit parameters are designed in detail,and a prototype of 200~400 V DC input,28 V DC output and rated power 1 kW is developed.The test results verify the correctness of the theoretical design.
