ABSTRACT:
A voltage regulator (12) for controlling and limiting the output voltage of an alternator (10) includes a control circuit having a full wave rectifier (28) for impressing a series of half wave pulses (32) onto a first circuit (34) in correspondence to the output of the alternator (10). A gate controlled switch (36) is utilized to conduct the half wave pulses (32) to the output circuit (24) when a gate signal is present. A voltage detector (44) monitors the output voltage and shunts the gate signal to ground when the output voltage reaches a given upper value and removes the shunt when the output voltage recedes to a given lower value.
