Mains independent electric brake for a locomotive

A line-side rectifier module (4n) connects via switches (12) to a brake resistance (15) that converts electrical energy created by an electric motor (2) during braking into heat. The switches connect via switching lines (18) to a device (19) for triggering a braking operation. A transformer connected in series to the rectifier module on the line side connects to the rectifier's first (9n) and second (10n) connectors via wires (7n,8n).
