Common-mode voltage (CMV) produces serious reliability and electromagnetic interference (EMI) issues in modern pulse-width modulated (PWM) electric drives. Such will become more prominent the near future, as industry moves towards introduction of wide-bandgap (WBG) semiconductor technologies operating at higher switching frequencies also with greater dvdt. In this context, multiphase drive can ...

This paper has described the application of the newly developed direct torque control (DTC) scheme for the reduction of common mode voltage of an induction motor drive. This DTC scheme for the reduction of common mode voltage does not use any zero voltage vectors. To validate the proposed algorithm, numerical simulation has been carried out using MATLAB-Simulink and results are presented and co...

This paper proposes a novel method based on pulse width modulation techniques toreduce and control the common-mode voltage in three-phase multilevel inverters. Besides controllingthe common-mode voltage, this method is capable of controlling capacitors voltages and load currentswith low switching losses and harmonic contents. In fact, due to the existence of different pulsepatterns and the poss...

An optimized space vector pulse width modulation (SVPWM) method with common mode voltage elimination and neutral point potential balancing is proposed for an open-end winding induction motor. The motor is fed from both of the ends with two neutral point clamped (NPC) three-level inverters. In order to eliminate the common mode voltage of the motor ends and balance the neutral point potential of...

The classical vector controlled algorithm gives variable switching frequency operation and increased harmonic distortion due to ...
