| Abstract: | IGBT is a sort of fully controlled power semiconductor devices developed lately, which has been widely used in the field of variable frequency speed control, switching power supply, etc. The problems such as parallel connection, driving and insulation in application of IGBT are reviewed and the performance of IGBT and SCR used in Large Scale Chopper Circuit is analyzed and contrasted in detail. The result shows that SCR is can not be substituted in large scale chopper circuit in the near future. |
