摘要
分析了基于TOP227的单端反激式开关电源的工作原理,运用动态小信号平均模型分析法, 对开关电源的主电路及控制电路组成的一个闭环控制系统进行数学模型的建立,并进行动态分析, 以求达到最佳的控制效果。
The working principle of the single ended flyback switching power supply by TOP227 is analyzed. By the way of dynamic little single average model analysis, a mathematics modeling of a close loop control system is found, which is composed of the switch power＇s main circuit and control circuit, and in order to attain the best of the control effect the dynamic analyzing is carried on.
