DIRECT CURRENT CONVERTER FOR MOTORS AND GENERATORS OF DIRECT CURRENT SERIES MOTORS

GLEICHSTROMSTELLER FUER DEN MOTORISCHEN UND GENERATORISCHEN BETRIEB DER GLEICHSTROM - REIHENSCHLUSSMASCHINE

Traction/braking switching of an induced circuit and excitation of the direct current series motors of the motive power units has generally been by means of contacts. This article describes an arrangement with thyristors and diodes for rapid change-over. The induced current and inducting current are uncoupled without the action of contacts. Another mounting for switching without inverse voltage protects against large voltage surges on the energizing winding. A simple extension of the mounting for regenerative braking and rheostatic braking is possible.
