This　paper　proposes　a　new　approach　to　ensure　the　torque　decoupled　to　the　rotor　flux　of　an　induction　machine　based　on　the　Field　Oriented　Control　(FOC).　The　suggested　method　consists　of　inserting　into　the　conventional　d-q　synchronous　current　controller,　coupling　terms　of　motor　and　multi-level　inverter　models.　Making,　the　dynamic　response　of　stator　current　components　decoupled　as　well　as　the　rotor　flux　and　torque.　In　this　paper,　the　mathematic　model　of　an　induction　motor　and　multi-level　inverter　are　first　derived.　Then,　the　synchronous　current　controller　and　modulation　strategy　for　high　power　inverters　are　investigated.　Finally,　the　validation　through　implementation　and　simulation　of　a　4.16　kV　electric　drive　with　MATLAB/Simulink　and　SimPowerSystems　is　performed.　The　model　simulated　in　this　paper　includes　an　induction　motor,　nine-level　cascaded　H-bridge　inverter　and　a　carrier　based　space　vector　pulse-width-modulation.　The　results　of　the　simulations　of　each　method　has　been　recorded　and　the　comparison　results　reveal　that　the　proposed　method　effectively　maintains　the　rotor　flux　decoupled　to　the　torque.　©　2018　Institute　of　Advanced　Engineering　and　Science.　All　rights　reserved.
