Zusammenfassung:	A voltage regulator and method are utilized in an automatic throttle control for an internal combustion engine driven inductor alternator. An SCR in series with the load is biased to conduct on successive positive half-cycles of a rectified a.c. input voltage. The SCR conductive bias is opposed responsively to the load voltage so that the average load voltage is a function of the number of complete pulses of the source in which the SCR conducts during a given time period. A hold-off circuit is provided to prevent SCR conduction during welding.
