However, traditional three-level inverters used to drive these motors often escalate system costs due to their large number of power switches. This article 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 article also propose a carrier-based pulsewidth modulation (PWM) scheme that uniquely imposes no computational burden on the microcontroller. This PWM strategy incorporates a 180 degrees phase shift between carriers of two three-phase systems, effectively eliminating common-mode voltage and xy harmonics. A comprehensive comparative study was conducted, assessing the proposed inverter against both two-level and conventional three-level inverters based on total harmonic distortion 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.eninfo:eu-repo/semantics/openAccessInvertersMotorsVectorsTopologyVoltageIndustrial ElectronicsPulse-Width ModulationCostsWindingsCapacitorsCommon-Mode Voltage (CMV) EliminationDiscontinuous Pulse-Width Modulation (DPWM)Dual Three-Phase MotorSparse InverterPulse Width ModulationCommon Mode Voltage (CMV) EliminationDiscontinuous Pulsewidth Modulation (DPWM)Article
