Several IGBT parallel methods for engineering application were introduced, and the technology cruces of IGBT directlyparallel were particularly presented. A IGBT parallel scheme for IGBT directly parallel was proposed, technology research and engineeringdevelopment of which including academic analysis, investigative experiments and operating test was processed. The results of experimentsindicated that the proposed parallel scheme had better current balancing and higher reliability, and had an extensive engineering applicationprospect.
