Resumo (PT): The paper presents the design, implementation, active protection against fault conditions and test results of a drive circuit for IGBT¿s 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, by using control signal modulated at high frequency and memory effect of the switch input. The main characteristics of the drive are requirements to an industrial application - the control of the drying and oil filling processing in the power distribution transformers industry. This application is based on a 100 kVA low frequency inverter implemented with IGBT transistors, 300 A, 1000 V.
