Generation-stop detection system of alternator

A generation-stop detection system of an alternator (1) is composed of a unit (48, 50, 52) for providing a generation-stop condition signal when output voltage of the alternator (1) is lower than a reference voltage, a rotation speed detection unit (40, 42), a reference-voltage changing unit (502, 5...

More Information
Summary:A generation-stop detection system of an alternator (1) is composed of a unit (48, 50, 52) for providing a generation-stop condition signal when output voltage of the alternator (1) is lower than a reference voltage, a rotation speed detection unit (40, 42), a reference-voltage changing unit (502, 506) which changes the reference voltage proportionally to the rotation speed of said alternator (1), and a warning signal unit (64, 84) which provides a warning signal if the generation-stop condition signal is provided at a rotation speed lower than a predetermined speed. The warning signal is maintained even if the rotation speed of said alternator (1) becomes higher than said predetermined speed. The warning signal is interrupted when the output voltage of said alternator (1) is higher than the voltage of the battery (80).
