However, traditional three-level inverters used to drive these motors often escalate system costs due to their large number of power switches. This paper introduces a dual three-phase sparse inverter designed to address these limitations. The proposed inverter utilizes only 16 power switches, a substantial reduction compared to conventional three-level inverters. This paper also propose a carrier-based Pulse Width Modulation (PWM) scheme that uniquely imposes no computational burden on the microcontroller. This PWM strategy incorporates a 180-degree phase shift between carriers of two three-phase systems, effectively eliminating common-mode voltage (CMV) in the topology. A comprehensive comparative study was conducted, assessing the proposed inverter against both two-level and conventional three-level inverters based on Total Harmonic Distortion (THD) and efficiency. To validate its performance, experimental results are provided for the proposed dual three-phase inverter driving a 746 W induction motor using a constant volt/Hz open-loop control method. © 2025 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/closedAccessCommon Mode Voltage (CMV) EliminationDiscontinues Pulse Width Modulation (DPWM)Dual Three-Phase MotorSparse InverterControllersElectric InvertersElectric Machine ControlFault ToleranceInduction MotorsIndustrial ElectronicsOpen Loop ControlTopologyVoltage ControlCommon Mode Voltage EliminationDiscontinue Pulse Width ModulationDual Three-PhaseDual Three-Phase MotorsInverter TopologiesModulation SchemesPower-SwitchesPulsewidth Modulations (PWM)Sparse InverterThree-Level InvertersPulse Width ModulationArticleN/AQ1
