N2 - Conventional pulse-width modulated inverters cause switching of common-mode voltage at the terminals of ac machines, which result in undesirable bearing currents and damage to the bearing. This paper presents a two- level indirect-matrix converter-based direct-link drive for three-phase open-end winding ac machines. The proposed topology suppresses common-mode voltage, outputs upto 1.5 times the peak input phase voltage and has controllable input power factor using a novel active filtering mechanism. Simulation results are presented that verify the operation of the proposed topology.
