Abstract
A power system for a vehicle comprises a first power supply network configured to operate at a first voltage. The first power supply network comprises a first alternator, a starter motor, and a battery conductively connected to the first alternator and the starter motor. The system further comprises a second power supply network configured to operate at a second voltage. The second power supply network comprises a second alternator, a power supply receptacle configured to output power to an external accessory, and a capacitive energy storage device conductively connected to the second alternator and the power supply receptacle. A directional conduction device interconnects the first power supply network and the second power supply network.
