Abstract

This paper shows the current and torque performance of a 750 W induction motor with a voltage unbalance compensator (VUC) when a DC link voltage is boosted using simulation. The VUC consists of a diode bridge, an inverter, and a voltage booster, however, DC voltage source was used in the simulation simply instead of the diode bridge and voltage booster. The VUC is connected to both of the power grid lines and the induction motor windings. It supplies compensating voltage and keep the terminal voltage balanced of the induction motor when the voltage unbalances occur on the power grid. It was cleared that the compensable range was expanded by boosting the DC link voltage of the VUC in the simulation. Besides, pulsation torque was also suppressed by voltage compensation enhancement. The current and torque waveforms were compered under three conditions such as without the VUC, with the VUC without boosted voltage, and with the VUC with boosted voltage. As a result, we clarified that the current and torque performance of the induction motor with the VUC is improved by the voltage booster even if the voltage unbalances factor increases.
