Abstract: A large capacity volage source inverter fed induction motor drive with a front-end three phase, three level ac to dc converter of neutral point clamping topology and parallel passive filter to the reactive power requirement is investigated. Ac supply current harmonics is reduced in this investigated topology. A control scheme is designed for the ac-dc front-end rectifier to vary the dc link voltage and regulate at any desired value. Total harmonic distortion of the ac supply current is evaluated and minimized. Input power factor is also made close to unity. The input power quality and drive system control performance both are improved. The simulation result confirms the improvement in input power quality and control performance of proposed drive scheme.
