	In this work, a 10-level inverter scheme ispresented to extend the linear modulation range (LMR) tillfull base speed operation of an induction motor (IM) drive.The increase in LMR is achieved by using a unique spacevector pulse width modulation(SVPWM) technique suchthat no lower order harmonics (such as5th,7th,11thand13th, etc.) are present in the phase voltage as compared tosix-step mode operation of conventional hexagonal spacevector structure (SVS) voltage source inverters. The pro-posed scheme can increase the peak phase fundamentalvoltage of the inverter from0.577Vdcto0.637Vdc(full basespeed operation), irrespective of the load power factor (p.f),whereVdcis the DC link voltage of the inverter. The 10-levelinverter structure is formed using a 2-level inverter andan H-bridge (HB) in cascade from one end and a floatingcapacitor-based 2-level inverter cascaded with an H-bridgefrom the other end to drive an open-end winding inductionmotor (OEWIM). All the HB capacitor voltages are balancedby using space vector redundancy. The claim of balancingthe capacitor voltages throughout the whole modulationrange is verified experimentally in this paper. Experimentalresults at different steady-state and transient conditionsare shown to validate the proposed inverter scheme’s ef-ficacy in increasing the LMR.
