An interface circuit for standard voltage regulator circuits that may be employed as an add-on component in an automotive electrical system for providing voltage regulation of the vehicle alternator in accordance with a given reference voltage that is in addition to the normal battery voltage regulation. The interface circuit includes a current control switching device coupled in the current path of the alternator field winding, and a control network responsive to the alternator output and the given reference voltage for operating said switching device in a duty cycle fashion so as to superimpose the additional regulation of the alternator voltage upon its normal battery regulation.
