**课程名称：电力电子基础** **课程概览：** 本课程将带您深入了解电力电子的基础知识，涵盖开关器件、逆变器、DC/DC 转换器等核心内容，并全程使用 LTspice 进行辅助教学。课程将重点讲解如何手动计算以及通过 LTspice 模拟不同波形下的开关器件功率耗散和热应力，包括散热器的选型以及判断是否需要主动散热。 此外，课程还将介绍硅（Silicon）、碳化硅（Silicon Carbide）和氮化镓（Gallium Nitrate）等开关材料，并分析它们的主要区别，帮助您根据具体应用选择最合适的材料。您将能够分析 DC/DC 转换器（Buck、Boost、Buck-Boost）和逆变器，理解电流在电路中的流动路径，并推导出输入与输出之间的稳态关系。 LTspice 将被广泛应用于验证计算结果、计算转换器效率，并指导您设计闭环 Buck 转换器。课程内容将通过练习题和实验环节得到充分的巩固。练习题旨在帮助您巩固所学知识，并提供详细的解答。实验环节则会引导您掌握 LTspice 的使用技巧。 我们鼓励您全情投入课程，投入足够的时间理解每个部分并完成练习题。我们相信，本课程将为您后续学习更高级的电力电子主题打下坚实的基础。
This course introduces you to the basics of Power Electronics including switches, Inverters, DC/DC converters and all that supported by LTSpice. We cover here how to calculate the power dissipation and thermal stresses for different groups of waveforms on switches by hand and using LTspice. That includes sizing the heat sink and enabling you to decide whether active cooling is required. We introduce you to Silicon, Silicon Carbide and Gallium Nitrate switches and the main differences to enable you to choose the best for an application. You will be able to analyse the DC/DC Converters: Buck, Boost, Buck-Boost and inverters and understand how the current flows in a circuit and to derive the steady state relations between the input and the output.LTSpice is used to validate the calculation and help to calculate a converter efficiency. We use LTSpice to design a closed-loop Buck converter. All that is supported by problem sets and labs. Problem sets are a group of problems that we supply for you to practice your understanding and we supply also the solutions. For the labs we introduce you to some tasks that will help you to conquer LTspice.We are expecting you to engage totally with the course and give enough time to understand each part and practice the problem sets. I am confident that will be an excellent course for you to understand any more advanced topics in power electronics.
