Analysis and Optimization Design of M57959L Module-Based IGBT Drive Circuit

With the rapid development of power electronics, IGBT has been more and more widely used because of its obvious advantages in consolidated performance. And the high-performance driving circuit directly affects its durability and service life. The comparable perfect drive and protection features of driver module M57959L enable it has already been widespread used. Some brief analysis of the module and its working principle characteristics are brought forward at the beginning of this paper. Then several improvements of IGBT drive circuit are put forward based on the analysis of its merits and deficiencies. In the end, the experimental figures have proven the rationality and the validity of this optimization program: it not only improves the drive capability of M57959L, but also enhances its anti-jamming ability. So the drive performance of IGBT could be more reliable.
