Abstract

Circuit configuration for degradation of the stored magnetic energy of a field winding of a generator, where a battery voltage is applied to the field winding, having a power switch that is in operative connection with the field winding and is controllable by timed pulses from a clock control and which controls the storage and degradation of energy of the field winding. A zener diode is arranged between the field winding and a control input of a power switch for control of the energy degradation of the field winding, in particular of the power switch.
