Power generation control apparatus for alternating current generator

Claim 2

A control apparatus for a vehicle alternating current generator means supplying an output voltage to a battery and an electric load connected across said generator means output voltage and said battery, said generator means having a field winding, said control apparatus comprising, in combination: voltage regulating means for controlling the output voltage of said generator means to a predetermined regulated value including a first switching means connected to detect the output voltage and operating to switch on and off at the predetermined regulated value; control means for controlling field current in said field winding in response to the operating of said first switching means to maintain the output voltage at the regulated value; second switching means connected to operate said control means independently of said first switching means so as to control the output voltage of said generator means independently of said first switching means upon the occurrence of an operating state; said second switching means including a temperature sensor for detecting the operating state temperature of at least one of the portions of said generator means which are subject to a self-heat generation; and an oscillator for generating an output signal oscillating at a conduction rate corresponding to the temperature detected by said temperature sensor.

Claim 3

A control apparatus for a vehicle alternating current generator means supplying an output voltage to a battery and an electric load connected across said generator means output voltage and said battery, said generator means having a field winding, said control apparatus comprising, in combination: voltage regulating means for controlling the output voltage of said generator means to a predetermined regulated value including a first switching means connected to detect the output voltage and operating to switch on and off at the predetermined regulated value; control means for controlling field current in said field winding in response to the operating of said first switching means to maintain the output voltage at the regulated value; second switching means connected to operate said control means independently of said first switching means so as to control the output voltage of said generator means independently of said first switching means upon the occurrence of an operating state; said second switching means including a temperature sensor for detecting the operating state temperature of the atmosphere around said generator means which is subject to a self-heat generation; and an oscillator for generating an output signal oscillating at a conduction rate corresponding to the temperature detected by said temperature sensor and coupled to operate said control means.
