   Abschliessend ist zur Ergänzung der Fig. 2 darauf hinzuweisen, dass gegebenenfalls zwischen die Motore 1 und   l* eine Glättungsdrossel   in Mittelpunktschaltung vorzusehen bzw. für den   Vorwärts- bzw.   



  Bremsstrom je eine halb so grosse Glättungsdrossel anzuordnen ist. 
 EMI2.1 
 :net, dass den den Umkehrantrieb bildenden Motoren (1 und 1') für den Vorwärtsbetrieb wenigstens ein Gefäss bzw. eine Gefässgruppe (2) zugeordnet ist, während für den Reversier- bzw. Bremsbetrieb nur einer   (1)   der beiden Motore mindestens mit einem nur für einen Teil der Nennspannung des für den Vorwärtsbetrieb vorgesehenen Gefässes bzw. Gefässgruppe (2) ausgelegten und zu diesem gegen-bzw. antiparallelgeschalteten Gefäss oder Gefässgruppe (3) verbunden ist.

   Finally, to supplement FIG. 2, it should be pointed out that, if necessary, a smoothing throttle should be provided between motors 1 and 1 * in mid-point connection or for the forward or



  Braking current a smoothing choke half as large is to be arranged.
 EMI2.1
 : net that the motors (1 and 1 ') forming the reversing drive are assigned at least one container or group of containers (2) for forward operation, while only one (1) of the two motors is assigned at least one for reversing or braking operation designed for only part of the nominal voltage of the vessel or vessel group (2) provided for forward operation Antiparallel-connected vessel or vessel group (3) is connected.

EMI2.4 Nennspannung des Motors (1) ausgelegt ist. versier or. The vessel or group of vessels (3) intended for braking operation is designed for approximately half the nominal voltage of the vessel or group of vessels (2) intended for forward operation. EMI2.3 The first converter transformer consists of six identical vessels (2) arranged in two identically dimensioned groups, while the vessel group (3) used for reversing or braking operation is formed from six identical vessels (3) which are also connected to two identically dimensioned groups are designed for about half the voltage as the nominal voltage of the vessel group (2) intended for forward operation. EMI2.4 Rated voltage of the motor (1). 5. Stromrichteranordnung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die aus je einem Gefäss beider Gefässgruppen (2 und 3) gebildeten und in Gegenparallelschaltung angeordneten Gefässpaare jeweils einem sekundärseitigen Wicklungsteil (4) des Stromrichtertransformators in Vorwärtsschaltung nachgeschaltet sind, wobei das Gefäss (2) der für den Vorwärtsbetrieb dienenden Gefässgruppe jeweils mit dem ganzen und das Gefäss (3) der andern Gefässgruppe mit einem entsprechenden Teil des Wicklungsteiles (4) verbunden ist. 5. Converter arrangement according to one of claims 1 to 4, characterized in that the pairs of vessels formed from one vessel each of both vessel groups (2 and 3) and arranged in counter-parallel connection are each connected downstream of a secondary-side winding part (4) of the converter transformer in forward connection, the vessel (2) the group of vessels used for forward operation is connected to the whole and the vessel (3) of the other group of vessels to a corresponding part of the winding part (4).
