Abstract
A vehicle based AC power system includes a specialized high efficiency vehicle alternator capable of supplying its maximum rated DC output current, even when being driven by an idling vehicle engine, to power a DC to AC inverter and provide maximum rated AC power at any engine speed. The alternator is preferably a wound field and permanent magnet hybrid alternator employing a three state bridge-type voltage regulator. An electrical load monitor electrically connected to monitor the electrical load on the alternator and a transmitter and receiver are used to remotely signal a user whenever there is an excessive load on the system.
