Abstract :
Common-mode voltages appear in PWM-CSI drives due to the working principles of the input rectifier and the output inverter. This work presents the modelling and analysis of the drive, by using the Matlab software to study this problem. The results of the model are in close agreement with experimental results, which show overvoltages of up to 100%, generating an important stress to the motor
