Abstract :
The paper presents the design, implementation, active protection against fault conditions and test results of a drive circuit for IGBT based static switches. Careful focus is concentrated on developing a drive qualified for protecting the switch in fault conditions, for controlling switching times in PWM inverter applications, for minimising noise effects of high frequency switching and not requiring any additional floating power supply. The main characteristics of the drive are required for an industrial application-the control of the drying and oil filling process in the manufacturing of distribution transformers. This application is based on a 100 kVA low frequency inverter implemented with IGBT transistors, 300 A, 1000 V
