Abstract
This paper introduces an induction machine with an implemented voltage unbalance compensator. Generally, voltage unbalances in the power grid line have been a serious problem for industrial motors due to over currents, torque ripple and local heating causes damage insulating material of stator windings. The induction machine with the implemented voltage unbalance compensator is consists of an open-winding induction machine and the voltage unbalance compensator (VUC) which is utilized PWM inverter and PWM converter. The stator windings of the induction machine are connected to the power grid line, the other side is connected to the VUC. The VUC provides the compensation voltages to the induction machine during the period unbalance voltage occurred. The torque ripple was compared with and without the VUC using a simulation. As a result, it was clarified the effectiveness for torque ripple reduction of the induction machine with the VUC.
