前言

当前，我国能源行业进行的供给侧结构性改革和能源转型变革，以及电网电能质量的保障和可再生能源的发电都离不开电力电子技术的支持。党的二十大报告明确提出，“加快节能降碳先进技术研发和推广应用，倡导绿色消费，推动形成绿色低碳的生产方式和生活方式”。这意味着越来越多的电能在进行能量转换之前需要进行多次电力电子变换，以实现用电设备的高效运行和电能最大化节约。电力电子技术是关于功率变换的技术，是在电气工程、电子科学与技术、控制理论三大学科基础上发展起来的新兴交叉学科。电力电子技术课程讲述了电力电子器件、电力电子电路的基本理论、概念和分析方法，其作为自动化、电气工程及其自动化或相关本科专业的一门重要专业基础课，将为后续专业课程的学习和今后的电力电子技术理论研究和工程实践打下良好的基础。
本书是 2022 年辽宁省一流本科课程（线下一流课程）、2024 年辽宁省首批省级普通高等教育课程思政示范课程“电力电子技术”、渤海大学 2023 年度校级规划教材（A 类）的配套建设教材。编者根据多年从事电力电子技术教学与科研工作的经验，在学习研究国内外优秀教材及其他相关文献的基础上，结合本校工程教育专业认证、国家级一流本科建设专业（自动化专业）建设实际，坚持政治标准和学术标准并重，思想性和科学性有机结合，完成了这本电力电子技术教材的编写工作。在保证本学科知识内容体系完整的前提下，精选内容、突出应用，教材编写中引入大量工
程案例，紧跟电力电子技术发展前沿，使教材内容更具有实用性，反映学以致用，遵循工程应用型人才的培养要求。
本书内容分为八章。绪论介绍了电力电子技术与其他学科之间的关系、发展史和电力电子技术的应用，让读者对电力电子形成感性直观的认识；第 1 章内容包括常用电力电子器件的工作原理、特性、参数、选型、驱动电路及保护方法；第 2 章至第 6 章，内容包括整流电路、无源逆变电路、直流-直流变换电路、交流-交流变换电路在内的常用电力电子变流电路的工作原理、参数计算方法和应用范围，还介绍了软开关技术，在这部分内容中结合应用实例较为详细地介绍了相控技术和 PWM 控制技术在上述各种电路中的应用；第 7 章从应用的角度出发列举了大量电力电子技术的应用案例，对电力电子技术在一般工业生产、电力系统、交通运输、新能源发电、信息技术、电子电气产品中的应用进行介绍，有助于学生了解所学理论知识在工程实践中的应用情况。
在讲清原理、注重应用的同时，深入挖掘课程思政元素，但限于篇幅，仅在各章末融入了思政案
例，部分体现了课程团队多年来的“三全育人”成果。电力电子技术是一门实践性很强的专业课程，需要大量的波形分析和计算，为了贯彻党的二十大报告中关于“加快建设国家战略人才力量，努力培养造就更多大师、战略科学家、一流科技领军人才和创新团队、青年科技人才、卓越工程师、大国工匠、高技能人才”。有关要求，本书在编写过程中注重应用型本科教学中实践技能的培养，融入了基于 Simulink 的图形化仿真技术。基本的教学内容配有仿真实验的实例，并提供了与理论分析波形相对应的仿真实验波形和实物实验波形，加强学生的感性认识和提高学生仿真应用能力。仿真实验指导循序渐进，便于初学者掌握与自学。
本教材按 54～64 学时编写，仿真实验可在课后或实践教学环节完成。本书编写过程中得到 2024 年辽宁省首批省级普通高等教育课程思政示范项目、辽宁省“兴辽英才计划”教学名师项目（项目编号：XLYC1906015）、2021 年辽宁省普通高等教育本科教学改革研究优质教学资源建设与共享项目（项目名称：跨校修读平台下的“电子技术”类课程资源建设与共享方式）、2023 年度渤海大学校级规划教材（A 类）、2022 年教育部产学合作协同育人项目
（项目名称：“工程认证+新工科”背景下电力电子技术实时仿真实验教学案例开发、项目编号：220603494132747）和 2023 年度渤海大学创新创业教学改革研究项目（A 类）（项目名称：工程教育认证背景下自动化专业产学合作协同育人能力映射与响应机制探索与实践、项目编号：0523jg084）资助。
