| Abstract |
In this paper a simplified mathematical model for the prediction of the conducted EMI generated by a
three-phase inverter is presented. The model allows the prediction of disturbances that propagates to
the DC bus and to the load, but special attention has been paid to the Common Mode (CM) current
disturbances at the load side. The model, that is based on the frequency domain, identifies the source
of disturbance and its propagation paths as well. The model is used to study an undesired effect that
take place in the induction motor drives: the circulation of CM currents through the motor. These
currents are the origin of many problems well described on the literature and many solutions have
been proposed to fix the problem. In this paper, two different vector modulation techniques are used:
the Classical Space Vector Modulation (CSVM) and the CM Reduction Space Vector Modulation
(CMRSVM). The experimental results obtained from the experimental plant has been compared with
those provided by the model in order to validate the model. |
