CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA speed control scheme is presented for a 3-phase permanent magnet synchronous machine with an open-end stator winding fed by a dual inverter system with a floating bridge. The floating bridge inverter is used to compensate the reactive power of the main inverter and, hence, to maximize the active power delivered to the motor in compliance with the constraints of a limited current and voltage. The DC-link voltage of the floating bridge varies depending on the operating condition of the motor in order to reduce the switching losses and ensure the controllability of the system. The experimental results show that a significant improvement in the width of the speed range at constant power is achievable in the flux weakening region. © 2018 IEEE.
