摘要： A temperature-controlled automobile voltage regulator comprising an emitter-coupled bistable circuit responsive to the alternator voltage for operating a current switch which so controls the current in the generator''s field winding that the alternator voltage bears a predetermined desired relationship to the ambient temperature of the regulator over a wide range of temperatures. A buffer stage, comprising an emitter-follower transistor amplifier, provides interstage coupling between the input and output stages of the bistable circuit. A temperature responsive circuit, comprising a transistor whose emitter-collector circuit is connected across part of the emitter resistance of the buffer stage, lowers the emitter resistance of the buffer stage as ambient temperature rises, thereby lowering the switching voltages of the bistable circuit. As a result the average current supplied by the current switch to the field winding of the alternator decreases, lowering the alternator''s output voltage as temperature rises, thereby to provide optimum battery charging.
