摘要/Abstract

摘要： 开关电源转换器是一个闭环网络控制系统，此系统存在高阶、离散、非线性和时变等特性。得到了一个CCM模式下脉冲宽度调制（PWM）控制的电流模BUCK变换器的小信号模型，该模型描述了系统稳态工作时的小信号特性。通过集成电路设计工具Virtuoso，利用AnalogLib库中理想器件得到关于近似函数的小信号模型。通过对小信号模型的稳定性仿真，能够预测电流模式控制的电源变换器的所有小信号特性，包括BUCK次谐波振荡的产生、斜坡补偿和补偿网络对系统稳定性的影响。

Abstract: Switching power converter is a closed-loop network control system, which has high order, discrete, nonlinear and time-varying characteristics. A small signal model of a current-mode BUCK converter controlled by pulse-width modulation (PWM) in CCM mode is obtained, which describes the small-signal characteristics of the system during steady-state operation. The small signal model of the approximate function is obtained by the integrated circuit design tool Virtuoso, using the ideal devices from AnalogLib library. Through the stability simulation of the small signal model, all the small signal characteristics of the current-mode controlled power converter can be predicted, including the generation of BUCK sub-harmonic oscillation, slope compensation and the influence of compensation network on the system stability.

Key words: DC-DC converter, pulse width modulation, system modeling, slope compensation, power management
