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.
