In recent years, the development of multiple three-phase drives for both energy production and transportation electrification has gained a growing attention. An important feature of the multiple three-phase drives is their modularity since they can be configured as three-phase units operating in parallel and using a modular control scheme. The multi-stator modelling approach represents a suitable solution for the implementation of modular control strategies able to deal with several three-phase units. Nevertheless, the use of the multi-stator approach leads to relevant coupling terms in the resulting set of equations. To solve this problem, a new decoupling transformation able to deal with a decoupled torque control of multiple three-phase induction motor drives is proposed. The experimental validation has been carried out with a modular power converter feeding a twelve-phase induction machine prototype (10 kW, 6000 rpm) using a quadruple three-phase stator winding configuration.

Abstract
In recent years, the development of multiple three-phase drives for both energy production and transportation electrification has gained a growing attention. An important feature of the multiple three-phase drives is their modularity since they can be configured as three-phase units operating in parallel and using a modular control scheme. The multi-stator modelling approach represents a suitable solution for the implementation of modular control strategies able to deal with several three-phase units. Nevertheless, the use of the multi-stator approach leads to relevant coupling terms in the resulting set of equations. To solve this problem, a new decoupling transformation able to deal with a decoupled torque control of multiple three-phase induction motor drives is proposed. The experimental validation has been carried out with a modular power converter feeding a twelve-phase induction machine prototype (10 kW, 6000 rpm) using a quadruple three-phase stator winding configuration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
