| Abstract: | The common mode voltage (CMV) is one of the main causes for the flow of bearing currents in induction motors. This in particular leads to damage of bearing parts and therefore causes serious problems. In addition, CMV may be the cause of an increase in electromagnetic interference problems. In this work, the space vector pulse width modulation methods are designed for three-level five-phase inverter (3LFPI) in order to eliminate the CMV. The choice of 3LFPI is based on the availability of those voltage vectors (VVs) that eliminate CMV. There are 41 non-vertex VVs available among total 243 that can eliminate the CMV. In this work, two different approaches have been developed. In first, large and a zero VVs are selected to eliminate CMV and to obtain maximum DC link. In second, large, small and zero VVs are selected to eliminate CMV and x–y stator plane. Both the proposed methods are validated through simulation and experimental results. [ABSTRACT FROM AUTHOR] |
