Abstract
An electrical apparatus for use with a motor vehicle electrical system, which includes an engine-driven alternator, provides a switching circuit for switching the system between a normal-power state and a high-power state. In the normal-power state, the apparatus provides the nominal electrical power needed by the vehicle electrical system and battery. In the high-power state, the apparatus causes the engine-driven alternator to produce a higher voltage and a higher power output for external loads, while still providing the nominal electrical power for the vehicle electrical system and the vehicle battery. In the normal-power mode of operation, the vehicle voltage regulator sees the full voltage generated by the vehicle alternator. In the high-power mode of operation, the vehicle voltage regulator sees only a reduced portion of the full voltage generated by the vehicle alternator. The increased power output from the alternator can be rectified into a high-voltage DC current or can be converted to 60 HZ 110-volt AC power by means of a cycloconverter, for example. A control circuit senses load current in the high-power mode of operation and causes the engine to operate at an increase…
