Abstract: A power supply device incorporated in a vehicle driven by an internal combustion engine including: a first power supply system for driving a vehicle load that converts an output of a generation coil provided in a generator driven by an internal combustion engine into a DC output to supply the DC output to an electrical load or electrical loads in the vehicle; and a second power supply system for driving an external load that converts an output of another generation coil provided in the generator into a DC output, then converts the DC output into an AC output at a commercial frequency with an inverter, and supplies the AC output to an external load, wherein the inverter is operated as a DC-DC converter to supply assisting power from the inverter through a switch to the first power supply system, when the output of the first power supply system is insufficient.

Abstract: A flywheel magneto generator which comprises a rotor having a magnet attached to an outer circumferential side of a flywheel and a stator constructed by winding a generating coil around a core having a magnetic pole portion opposed to a magnetic pole of the rotor, wherein a through hole is formed in a peripheral wall portion of the flywheel, a yoke plate is provided so as to block one end of the through hole which is opened on an inner circumferential side of a peripheral wall portion of the flywheel, the magnet to which a magnet cover is attached is supported on the yoke plate, and one magnetic pole face of the magnet is opposed to the yoke plate.

Abstract: A generator apparatus driven by an internal combustion engine and comprising a revolution controller to control a revolution of the internal combustion engine so as to maintain a desired value of a terminal voltage of a battery which is charged by an output of an AC generator driven by the internal combustion engine while controlling an actuator for operating a fuel supply adjuster, an engine start controller to give a start instruction from a timer circuit to start means when the battery is discharged until the terminal voltage is lowered to a set value and an engine stop controller to give a stop instruction from the timer circuit to stop means when the battery is perfectly charged by the operation of the engine until the revolution of the engine is lowered to a stop revolution thereof whereby the starting and stopping operations of the engine are controlled without undercharging and overcharging the battery.

Abstract: A discharge lamp lighting device driven by an internal combustion engine is disclosed which is capable of lighting a discharge lamp without using a ballast constituted by a leakage transformer. The device includes a generator which is driven by the internal combustion engine and of which output characteristics exhibit drooping characteristics, so that an output voltage of the generator may be applied to a discharge lamp without using any ballast. Output characteristics of the generator are so set that an output voltage of the generator at a non-load state thereof may be higher than a break-down voltage of the discharge lamp, a shortcircuit current of the generator may have a level sufficient to restrict a discharge current of the discharge lamp just after starting of discharge thereof to an allowable level or below, and a voltage across the discharge lamp and a discharge current thereof at a steady state thereof each are kept within a rated range.
