Abstract
The utility model discloses a generator regulator circuit for starting an automobile with a low rotation speed under the condition of the application of a light-emitting diode as an indication lamp, and belongs to the generator regulator circuit. The generator regulator circuit comprises a voltage regulation circuit, a signal sensing circuit, a switch circuit, and an extra excitation circuit. When an automobile ignition switch is on, a power triode is conducted, and the signal sensing circuit senses and then transmits a signal to the switch circuit which is then conducted to allow the current of an accumulator to enter into an generator rotor via the extra excitation circuit, so that the excitation current of the generator is increased, and the start-up rotation speed of the generator is reduced. When the automobile ignition switch is off, the power triode is closed, and the signal sensing circuit transmits the signal to the switch circuit which is then closed to break the connection between the regulator and the accumulator so as to realize zero leakage current. The generator regulator circuit has the advantages that the power generating rotation speed of the generator is reduced; the current leakage is prevented; and the operating consumption of a power tube is reduced to increase the output power of the generator.
