针对电流型DC-DC变换器分析了三种经典的补偿网络设计,并给出了三种补偿网络的传递函数.结合单路输出电流型单端正激DC-DC变换器设计满足一定要求的三种具体补偿网络.应用网络分析仪Agilent4395A实测引入三种补偿网络后的频域性能.在负载50％-100％跃变时实测引入三种补偿网络后的时域性能.通过分析对比引入三种补偿网络后的频域和时域特性,总结分析结果给出了三种补偿网络的特性表.%Three kind of classical compensation network for DC-DC converter are analysed and presentsed the transfer function for compensation network. To aim at the demand characteristic, three compensation network are designed for the forward converter based on current-mode. The amplitude-frequency characteristic and phase-frequency characteristic are tested by the network analyzer Agilent4395A. The step response are tested under the load changing from half to full. Comparing and analyzing the test results, the characteristics of the compensation network are shown in one form.
