Abstract
A regulator for a vehicle charging system senses when it applies and terminates excitation to the field winding of the charging system's alternator. When the excitation is applied to the field windings, the output of the alternator is connected to an input filter in the regulator so that the regulator can sense the alternator's output. When the excitation is terminated, the input filter is disconnected from the alternator's output to isolate the filter from voltage steps induced in the alternator's output by the turn-on and turn-off of the field excitation.
