【摘要】：随着电动车、高速动车等行业的迅猛发展,电力电子也进入了高速发展的快车道,IGBT作为高电压,大功率的换能器件,具有输入阻抗大,导通压降小、驱动电路相对简单等优点,作为大功率的换能转换器件,也受到了越来越多的关注。而IGBT的价格相对较高,又工作在高压,大功率的环境中,易损坏,所以IGBT的驱动电路设计中要做到对IGBT充分的保护功能,所以越来越多的研究IGBT驱动电路的研究被大家重视。本文是基于电动车控制器,简要介绍了控制器的各个功能模块,主要针对控制器中IGBT的选型、工作特性等方面进行介绍,。分析了IGBT的工作原理,IGBT驱动电路的设计要求以及注意事项,列举了几种目前常见的有效抑制IGBT开关过程中反峰电压的方案,并提出了一种新的上下臂结合新方法,通过理论分析,及Cadence中的OrCAD仿真模块进行仿真,验证了方案的有效性和可行性。同时还简要介绍了IGBT的发热损耗和短路保护等。最后从整体上对本文进行了总结,指出了本课题的不足与需要改进之处,并对课题的下一阶段工作做了简单的规划。读者读完此篇文章会对IGBT的基础以及发展现状有了一个整体的初步认识。
[Abstract]:With the rapid development of electric vehicles, high-speed motor cars and other industries, power electronics has also entered the high-speed development of fast lane IGBT as a high-voltage, high-power transducer, with the advantages of large input impedance, small on-voltage drop, relatively simple drive circuit, etc.As a high power conversion device, more and more attention has been paid to it.The price of IGBT is relatively high, and it is easy to be damaged in the environment of high voltage and high power. Therefore, the design of IGBT drive circuit should provide sufficient protection to IGBT, so more and more researches on IGBT drive circuit are paid more and more attention to.This article is based on the electric vehicle controller, briefly introduces the controller each function module, mainly carries on the introduction to the controller in the controller IGBT selection, the work characteristic and so on aspect and so on.This paper analyzes the design requirements and points for attention of the IGBT driving circuit, enumerates several common schemes to effectively suppress the reverse peak voltage in the process of IGBT switch, and puts forward a new method for the combination of upper and lower arms.The effectiveness and feasibility of the scheme are verified by theoretical analysis and OrCAD simulation module in Cadence.At the same time, the heat loss and short circuit protection of IGBT are briefly introduced.Finally, the paper summarizes the whole paper, points out the shortcomings and needs improvement, and makes a simple plan for the next stage of the project.After reading this article, the reader will have a general understanding of the foundation and development of IGBT.
