| 摘 要： | 基于能量守恒模型，在求取主电路G参数的基础上，对含前馈Boost变换器电路的动态低频特性进行分析，比较了含前馈电路和不含前馈电路的动态小信号特性。从分析中可以看出，工作于连续导电模式，含前馈电路能较好地抑制电路的线性扰动，从而提高电路的稳定性和动态特性，仿真实例表明，该方法模型简单，精度较高，且易于理解和编程。

| Abstract: | Based on modeling of energy conservation and request of the G parameters of the main circuit, dynamic characteristics are studied for the Boost converter with input voltage feed forward control, and the small signal characteristics are compared for both the converter with feed forward control and the converter without feed forward control. Analyses indicated that the converter with input voltage feed forward control can reduce the linear disturbance working in the continuous conduction mode, so as to improve the stability and dynamic characteristic. The results of simulation show that this method possesses simplicity and very high precision, and are easy to be understood and to be programmed. |
