N2 - This work presents a predictive strategy that effectively mitigates common-mode voltages from power converters, that cause overvoltage stress to the winding insulation and bearings deterioration, reducing the lifetime of electric machines. The strategy must be implemented under a predictive current control method that replaces modulation stages and linear current controllers, usually employed with PWM-converters. The method was experimentally tested on a matrix converter feeding an induction machine, with different load conditions. As a result, common-mode voltage was mitigated in 70%, reducing abrupt changes without affecting the performance of the drive.
