Description
Summary:This paper is focused on the investigation of performance and improvement of the switching control of high voltage IGBTs especially when connected in series. A variety of seriesing methods are explored and valuated. Due to the dominant advantages the Active Voltage Control (AVC) strategy is characterized, analyzed and optimised in simulation and experiments. A new method Active Voltage/Current Control (AV/CC) is advanced and validated for di/dt control. It is concluded that the AVC, particularly with the di/dt auxiliary loop control, allows the operation of high power IGBTs in series to be closely defined and well controlled.
