| Abstract(in English) | An AC motor drive system using an inverter generates common mode noise. However，a common mode noise filter becomes bulky. To eliminate the common mode noise filter, we proposed two motors operating in opposite phase method. An equivalent circuit model that takes into account the dispersion in common mode impedance of each motor is constructed to predict the noise reduction effect of the proposed method. However, there is a problem that the prediction accuracy at low frequency range is low. In this paper，prediction accuracy of the common mode noise at low frequency range has been improved by an each phase equivalent circuit model. The effectiveness of the proposed method is evaluated by the circuit simulation and the experimental results. |
