Outline of Final Research Achievements

This program studied the control method of the dual inverter drive opening winding induction motor for the purpose of high efficiency of motor Drive System used for electric cars. The proposed system establishes one DC power supply and capacitor in the DC link of each inverter and has the control method to balance capacitor voltage control with motor speed control. Peak voltage level control (PAM) of the applied voltage depending on a state of the impossible motor speed and multilevel inverter operation became available for high efficiency operation of the low speed area.The proposed system achieves motor loss from 52.6[W] to 48.2[W] in comparison with the conventional system. Furthermore,the proposed system achieves total loss from 66.1[W] to 58.4[W] in comparison with the conventional system.
