| 摘 要： | 电流控制模式的补偿网络比电压控制模式的补偿网络容易调整,但是前者的建模要比后者的建模复杂得多。采用状态空间平均法为峰值电流控制有源箝位正激变换器建立了小信号模型,分析了箝位电路对变换器动态性能的影响,并给出了补偿网络的设计方法。

| Abstract: | The parameters adjustment of compensate part in peak-current control mode power supply comes more easy than that in voltage control mode. However, model of the former is more complicate than that of the latter. This article uses the state-pace average method to get the small-signal model of active-clamp forward converter with peak-current control mode, then analyses the influence of the active-clamp circuit to the entire converter, finally present the design method of the compensate network. |
