Abstract
An alternator system includes an alternator with a stator having at least one stationary winding and a rotor with a rotatable field coil for producing alternating current, a main voltage regulator having a main controller and a main power switch configured to control the current through the field coil, a redundant voltage regulator having a redundant controller and a redundant power switch configured to control the current through the field coil. The main power switch, the field coil and the redundant power switch are connected in series, in that order. A power supply for an electrical system includes a battery and the alternator system. A vehicle includes the power supply.
