摘　　要：本文首先介绍了一种54W抗辐照DC／DC电源中MOSFET、肖特基、输出滤波电感、变压器、UC1843和UC1901损耗的计算方法。其次根据计算结果预计电源的效率。最后将效率预计值和模拟实验值效率值以及实际产品效率值进行对比，并分析其差异的原因。This paper firstly introduces the loss calculation method of MOSFET, schottky, output filtering inductor, transformer, UC1843 and UC1901 for 54W radiation hardened DC/DC converter. Secondly the efficiency of DC/DC converter is predicted according to the calculation results. Finally we compared the efficiency prediction values with simulation experimental values and practical efficiency of the product, also with the reasons for the differences are analyzed.
