    Nine-switch inverter for driving two induction motors independently
    (2019) Laloui, Mahdi; Rebbouh, Khaled; Metidji, Brahim (Supervisor)
    Industrial applications require large numbers of motors supply in the industrial world; therefor it is necessary to design system with low cost, reduced losses and higher efficiency. The nine-switch inverter is a recent reduced semiconductor topology which is developed to dual output converter. It can be used to drive two three-phase induction motors independently. As a substitute of two separate voltage source inverters, the nine-switch inverter has been already proposed in various industrial applications to reduce the number of semiconductor switches and energy losses. In this context, a scalar control method is developed to ensure the separate control of both induction motors. Simulations then implementation are carried- out to show that the developed independent control is effective and provides a simple configuration with high performance in terms of speed and torque responses.
