ABSTRACT:
The voltage regulator includes a voltage regulation electric circuit stage, an output electric circuit stage and an optic coupler connecting but electrically isolating said stages. The input of the voltage regulation stage is connected to a battery and/or directly or indirectly to the power output terminal of a direct current alternator or generator and the output of the voltage regulation stage is connected to the light emitting diode of the optic coupler the phototransistor of which is connected to a transistor switch in the output electric circuit stage which functions to connect the field windings of the alternator or generator to the same battery or to another battery in series with said battery, and/or to the power output terminal of the alternator or generator. When employed with series-connected batteries and the dual voltage control described in applicant's earlier U.S. Pat. No. 4,041,363 the input of an electronic on-off timer may be connected across the lower voltage battery of the series with the output of the timer connected to the voltage regulation stage to turn the latter on and off a predetermined timed sequence.
