Performance Enhancement of Wound Rotor Induction Motor by VSI with Dynamic Capacitor

SKU: 010402


The work proposes a novel method for improving performance of a Three Phase wound rotor induction motor using an indirect reactive current control method in the rotor a 3-phase VSI with a dynamic capacitor is connected in the rotor circuit used for controlling the reactive current in the rotor and the dynamic capacitor is an H-bridge switch by a capacitor in which the duty ratio of the H-bridge circuit is various in order to change the capacitance value dynamically. The performance parameters such as the torque, speed, rotor current and stator Current are obtained. In addition to improving performances, as the future method uses only one capacitor in the rotor whereas against three capacitors are used in the rotor impedance control scheme.
