Abstract
A circuit for the energy-conserving braking of an electrically powered vehicle having a series-wound direct-current motor with field winding and armature connected in series with a high-ohmic resistance across the battery connection is effected by a main thyristor is provided with a second thyristor serving to quench the first thyristor. A capacitor (quenching capacitor) is included in a commutating device or network parallel to the main thyristor. A voltage sensor responsive to the voltage level at the junction between the condenser and the main thyristor controls the commutating circuit.
