电气工程论文 摘 要 随着电力电子技术的发展，功率器件在不断地更替。从结型控制器件，如晶闸管、GTR、GTO，到场控器件，如功率MOSFET、IGBT、IGCT,他们的体积不断地缩小，功率不断地提高，电气特性越来越优化，使得基于它们生产出来的产品，外观和性能都得到了很大改善。IPM智能功率模块是一种新型功率开关器件，是以ＩＧＢＴ为基本功率开关元件构成三相逆变器的专用功能模块，它继承了GTR和MOSFET的优点，其最大特点是集功率变换、驱动保护电路于一体。提高了系统的可靠性，使用起来十分方便。本文设计是以三菱公司的IPM—PM50CLA120例，用PROTEL软件来设计它的驱动板的原理图和PCB图。然后再做出驱动板的实物。用该驱动板去驱动IPM—PM50CLA120，以使三相异步电机在IPM—PM50CLA120的驱动下运转。再输入SPWM信号，测试IPM的驱动驱动信号的波形和三相异步电机的电流波形。实验证明驱动板能较好地工作。 关键词：智能功率模块、驱动板 目 录 摘要…………………………………………………………………………….…………….…… I 1 前言……………………………………………………………………………………………. 2 2 智能功率模块…………………………………………………………………………………3 2.1 IPM的内部结构……………………………………………………………….………...4 2.2 IPM的性能特性……………………………………………………………………...….4 2.21 IPM的优点 … ………………………………………………………………...5 2.2.2 IPM的额定值和特性 ………………………………………………………...6 2.2.3 IPM 的安全工作区 ……………………………………………………………7 2.2.4 IPM的自保护功能 ………………………………………………………….10 2.3 IPM的发展和应用…………………………………………………………………….11 2.3.1 IPM的发展 ……………………………………………….…………………..12 2.3.2 IPM的应用 …………………………………………………………………...12 3 智能功率模块的驱动板设计………………………………………………………………13 3.1 IPM的驱动原理……………………………………………………………….……….14 3.2 用Protel设计IPM的驱动板…………………………………………………………....15 3.2.1 驱动板原理图的设计…………………………………………………………..17 3.2.2 驱动板PCB图的设计………………………………………………………….19 4 智能功率模块的驱动测试………………………………………………………………….20 4.1 驱动测试说明…………………………………………………………………………….20 4.2 输入信号PWM简介……………………………………………………………………..21 4.3 驱动测试的波形………………………………………………………………………….24 5 总结…………………………………………………………………………………………..25 致谢……………………………………………………………………………………………….26 Abstract With the development of power electronics, power devices continues to change. From the node control device, such as Thyristor, GTR, GTO, to the scene controller devices, such as power MOSFET, IGBT, IGCT, their size are reducing ,and power are continuing to increase, becoming more and more optimize electrical characteristics, making them based on production out of products, the appearance and performance have been greatly improved. Intelligent Power Module IPM is a new type of power switching devices, based on IGBT power switching components for the basic three-phase inverter constitutes a special function module, it inherits the advantages of GTR and the MOSFET, and its most prominent feature is a power transformation, drive protection integrated circuit. Improved the reliability of the system is very convenient to use. In this paper, the design is based on Mitsubishi IPM-PM50CLA120 cases PROTEL software used to design the driver board schematic and PCB Fig. Driver board and then make the kind. Use this board to drive plate IPM-PM50CLA120, to enable the three-phase asynchronous motor in the IPM-PM50CLA120 driven operation. Then input SPWM signal , test the drive signal waveform of IPM and three-phase asynchronous motor’s current waveform. Driver board can be proved to work well.
