开关电源的频域分析与综合(Ⅰ)

Analysis and Synthesis of Switching Regulators in frequency domain(Ⅰ)

开关变换器的线性平均模型是一个线性时不变(LTI)电路,瞬态分析和控制设计(综合)的传统方法是频域法,即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。

The linearized averaging model of a switching converter is a linear time-invarient (LTI) circuit. Traditionally, the frequency domain approach is often used for the transient analysis and control design (synthesis) of the switching power supply, that is: to investigate its transient behaviors in frequency domain, such as: stability, fastness, robustness, line and load rejections etc.
