摘要
Common-mode voltages appear in pulse-width modulated current-source inverters (PWM-CSIs) drives due to the operating principles of the input rectifier and the output inverter. This paper presents the modeling and analysis of. a medium voltage current-source inverter drive, using the Matlab software. Simulated results of the model are in close agreement with experimental waveforms; obtained from an industrial ac drive, which shows over-voltages of up to 100%, generating important insulation stresses at the motor stator terminals.
