The authors have successfully developed a type of 120 kVA special frequency convertor. And a new practical drive module 2SD315A was chosen to solve the problems on driving high power IGBT. This paper expounds the interior structure, the main capability of the module 2SD315A, and the practical effect of the drive circuitry based on it.
