English | PDF,EPUB | 2018 (2019 Edition) | 248 Pages | ISBN : 9811325731 | 17.35 MB

This book focuses on the applications of Equivalent-Small-Parameter Method (ESPM) in solving the steady-state periodic solutions, as well as stability analysis, of kinds of open-loop or closed-loop operated DC/DC converters, such as PWM, quasi-resonant and resonant ones. The analytical expressions of DC components and harmonics of state variables (inductor current and capacitor voltage) with DC/DC converters can be obtained by ESPM, which can be helpful to understand the nonlinear operating mechanism of switched-mode converters. It can also be useful for stability analysis and design for practical converters. Modeling and analysis on all kinds of DC/DC converters are introduced in detail in this book, along with a large amount of simulation or experimental waveforms to verify the correctness of the theoretical analysis based on ESPM.


这本书专注于使用等效小参数法(ESPM)来解决各种开环或闭环操作的DC/DC转换器,如PWM、准谐振和谐振式转换器的稳态周期性解以及稳定性分析。通过ESPM可以得到DC/DC转换器状态变量(电感电流和电容电压)的直流分量和谐波的解析表达式,这有助于理解开关模式转换器的非线性工作机制。它还可以用于实际转换器的稳定性和设计分析中。本书详细介绍了各种DC/DC转换器的建模与分析,并通过大量的仿真或实验波形来验证基于ESPM的理论分析的正确性。
