Abstract

The three-phase bridge consists of distribution diodes and associated commutating capacitors and can be quenched. A commutating capacitor is associated to the quenchable diodes of both bridge halves. Each commutating capacitor is corrected to one pole of a d.c. voltage source via a quenching thyristor. Two groups of distribution diodes in star connection are each connected in the same direction and in parallel to the three motor phases, with the individual groups being connected in parallel. The star points are each connected, via a further quenching thyristor with the free terminal of the associated commutating capacitor. From the star points of the distribution diodes (11a - c, 12a - c) leads an additional free wheel circuit each to both poles of the d.c. voltage source (8). The free wheel circuit comprises change-over oscillation diodes (25,26).
