Abstract
A voltage regulating system for an automotive vehicle having a switching transistor connected to a field winding of an alternating current generator and a regulator for comparing a battery voltage with a reference value and for driving the transistor into a conductive state when the battery voltage is lower than the reference value. A current limiting circuit is provided for limiting the field current when the switching transistor is going to be driven into the conductive state over a predetermined interval, so that a maximum charging current can be obtained and an unfavorable heating of the switching transistor can be avoided.
