摘要
开关稳压电源瞬态分析的核心问题是建立一个恰当的模型。瞬态分析包括大信号分析、小信号分析和直流分析。系统瞬态分析和设计(综合)的传统方法是频域法,在复频域内研究分析开关电源的瞬态性能,如:稳定性、鲁棒性、快速性和对输入电压或负载的抗扰动性等。给出了电压型控制的开关电源单环系统的频域模型,以及系统的频域分析、设计(综合)方法。讨论了电压控制器(补偿网络)的参数选取及双环(电流型)控制的开关电源建模.
The appropriate modeling is a central to the transient analysis of a switching regulator, including large signal analysis,small signal analysis and DC analysis. Traditionally, the frequency domain approach is often used for the transient analysis and control design （synthesis） of the switching regulators, that is： to investigate the transient behaviors of the switching voltage regulators in frequency domain, such as： stability, fastness, robustness, line and load rejections etc. The models in frequency domain of the single-loop （voltage-mode control） switching regulators and also the transient analysis and design approach of switching regulators are presented. The parameters selection of voltage controllers and modelling of the two loop （current mode control） SMPS are also discussed.
