GaN transistors allow to achieve higher switching frequency with high efficiency. However, the rapid voltage rise at the output is the main challenge to utilize full potential of GaN based variable frequency drives for three phase motors. The paper provides experimentally based designs of the inverters with limited slew rate of the switching actions at the output to utilize higher switching frequency and improve performance of the motor drive.
