一种新型实用的IGBT驱动电路

A New and Practical Drive Circuit for IGBT

在分析了IGBT驱动条件的基础上介绍了几种常见的 IGBT驱动电路，并给出了各自的优缺点。给出了自行设计的一种简单、实用的新型IGBT驱动电路。经实践表明，该电路经济、实用、安全、可靠，同时具有IGBT过电流保护功能，具有很好的应用前景。

A few ordinary drive circuit for IGBT are introduced in this paper, their virtue and drawback was also introduced. A new and practical drive circuit for IGBT designed by ourselves was introduce at last. It has been testified by practice that it is economical、utility、safety、credibility, and is can protect IGBT from over current. It should be widely used in future.
