Title
(EN) VARIABLE RELUCTANCE MOTOR SYSTEMS
(FR) SYSTEMES MOTEURS A RELUCTANCE VARIABLE
Abstract
(EN)
A variable reluctance electric motor system includes a variable reluctance motor having a main winding for each phase and a power converter circuit including a main thyristor in series with each main winding connected across a direct voltage source from which the main windings are supplied sequentially with uni-directional current pulses, characterised by a commutating thyristor (16) for starving the main thyristor (12) of the current flowing through one main winding (11) while charging a capacitor unit (51, 52) in one sense, and a commutating thyristor (26) for starving the main thyristor (22) of the next phase winding (21) of the current flowing through the next main winding (21) while charging the capacitor unit in the other sense. The arrangement is such that commutation of a main thyristor initiated by firing a commutating thyristor and terminated when this commutating thyristor ceases to conduct, leaves the commutating capacitor unit charged with the correct polarity and adequate voltage for the commutation of the next main thyristor in the conducting sequence.

Un systeme moteur electrique a reluctance variable comprend un moteur a reluctance variable ayant un enroulement principal pour chaque phase et un circuit convertisseur de puissance comprenant un thyristor principal en serie avec chaque enroulement principal connecte a une source de tension a courant continu qui alimente les enroulements principaux successivement avec des impulsions de courant uni-directionnelles, et se caracterise par un thyristor de commutation (16) qui prive le thyristor principal (12) du courant passant a travers un enroulement principal (11) tout en chargeant un condensateur (51, 52) dans un sens, et un thyristor de commutation (26) pour priver le thyristor principal (22) de l"enroulement de phase suivant du courant passant au travers de l"enroulement principal suivant (21) tout en chargeant le condensateur dans l"autre sens. La disposition est telle que la commutation d"un thyristor principal initiee par allumage d"un thyristor de commutation et terminee lorsque ce dernier cesse d"etre conducteur, laisse le condensateur de commutation charge avec la polarite correcte et la tension adequate pour la commutation du thyristor principal suivant dans la sequence de conduction.
