摘  要
 隨著電力電子技術的發展，功率器件在不斷地更替。從結型控制器件，如晶閘管、GTR、GTO，到場控器件，如功率MOSFET、IGBT、IGCT,他們的體積不斷地縮小，功率不斷地提高，電氣特性越來越優化，使得基于它們生產出來的產品，外觀和性能都得到了很大改善。IPM智能功率模塊是一種新型功率開關器件，是以ＩＧＢＴ為基本功率開關元件構成三相逆變器的專用功能模塊，它繼承了GTR和MOSFET的優點，其最大特點是集功率變換、驅動保護電路于一體。提高了系統的可靠性，使用起來十分方便。本文設計是以三菱公司的IPM—PM50CLA120例，用PROTEL軟件來設計它的驅動板的原理圖和PCB圖。然后再做出驅動板的實物。用該驅動板去驅動IPM—PM50CLA120，以使三相異步電機在IPM—PM50CLA120的驅動下運轉。再輸入SPWM信號，測試IPM的驅動驅動信號的波形和三相異步電機的電流波形。實驗證明驅動板能較好地工作。

關鍵詞：智能功率模塊、驅動板

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.

Keywords：Intelligent power module、 the drive plate
