Title (EN) DEAD TIME COMPENSATION USING AN ERROR VOLTAGE CALCULATION
(FR) COMPENSATION DE TEMPS MORT AU MOYEN D'UN CALCUL DE TENSION D'ERREUR
Abstract:
(EN) Systems and methods for controlling an electric motor are disclosed. The electric motor may be powered by a DC power source using an inverter, and may be used to power an electric vehicle. Error voltages, corresponding to average voltage loss over a switching period due to inverter switching dead time, can be calculated for each phase of the inverter. The error voltages may be converted to alpha and beta error voltages and used to generate duty cycle commands to drive the electric motor. Correction terms may further be applied to avoid unnecessary voltage increases at low phase currents and high modulation indices.
(FR) L'invention concerne des systèmes et des procédés de commande d'un moteur électrique. Le moteur électrique peut être alimenté par une source d'alimentation en CC au moyen d'un onduleur et peut être utilisé pour alimenter un véhicule électrique. Des tensions d'erreur correspondant à une perte moyenne de tension sur une période de commutation en raison d'un temps mort de commutation d'onduleur peuvent être calculées pour chaque phase de l'onduleur. Les tensions d'erreur peuvent être converties en tensions d'erreur alpha et bêta et utilisées pour générer des instructions de cycle de service pour entraîner le moteur électrique. Des termes de correction peuvent en outre être appliqués pour éviter des augmentations de tension inutiles à des courants de phase faible et des indices de modulation élevés.
