Abstract: A regulator for a vehicle. The regulator includes an input stage configured to be operatively connected to the AC generator of the vehicle; an intermediate circuit electrically connected to the input stage; an output stage electrically connected to the intermediate circuit and configured to be connected to a battery of the vehicle; and a microcontroller communicatively connected to the input stage, the intermediate circuit, and the output stage. The input analog voltage controller assembly is configured and arranged to adjust the DC signal provided to the intermediate circuit to a voltage potential of approximately 60V. The microcontroller is configured to control the output stage to selectively vary the output voltage of the regulator, the output voltage being selectively variable between 0 V and 14.5 V.
