摘　　要：以实际案例为样本,针对36 W反激式开关电源的效率测试问题,结合Co C与DOE的相关标准,分别选用轻载降频模式以及传统PWM模式的开关电源芯片进行效率对比实验,希望通过效率测试实验的数据给出具有实际应用意义的结论。The thesis uses practical cases as samples, focusing on the problem of efficiency tests of 36 W flyback SMPS. Combined with related standards of Co C and DOE, the efficiency comparison experiments of two flyback SMPS ICs respectively with light load frequency down mode and traditional PWM mode are performed. The thesis tries to give a conclusion with actual application significance by using the results of efficiency test.
