Circuit arrangement for supplying a reluctance motor

摘要

A circuit arrangement for supplying a reluctance motor is described, comprising a D.C. voltage source having an asymmetric H-circuit for each winding (12, 13, 14) of the motor. In it, a first series arm (1, 5) is common to all the H-circuits and, in addition, each H-circuit has a second series arm (2, 6 or 3, 7 or 4, 8 respectively). Both series arms are arranged between terminals (9, 10) of the D.C. voltage source and each contain a switching element (1 or 2 or 3 or 4, respectively) and, arranged in series therewith, polarised in the reverse direction with respect to the D.C. voltage source, a rectifier element (5 or 6 or 7 or 8, respectively). The switching element (1 or 2 or 3 or 4, respectively) of the one series arm and the rectifier element (5 or 6 or 7 or 8, respectively) of the other series arm are, in this case, connected on one side with one and the same terminal (9 or 10, respectively) of the D.C. voltage source and the corresponding winding (12 or 13 or 14, respectively) is arranged in the cross-branch of the H-circuit, between the connections of the switching element (1 or 2, 3, 4, respectively) and of the rectifier element (5 or 6, 7, 8, respectively) of each series arm. This arrangement is constructed very simply and economically and allows optimal regulation of the reluctance motor.
