7.2.1. General information
The system of power supply serves for additional charge of the storage battery on the car.
At rotation of the coil of excitement on which the electric current is passed, in windings of a stator the alternating voltage is directed.
By means of vypryamitelny diodes the alternating voltage of the generator becomes straight. The schedule of the straightened tension is shown in drawing.
Average value of the straightened tension slightly changes depending on loading.
At ignition inclusion on a winding of excitement the current from the storage battery is passed, providing initial excitement of the generator. After engine start excitement of the generator is provided at the expense of the tension induced in windings of a stator. Target tension of the generator increases with increase in a current of a winding of excitement and decreases with reduction of a current of a winding of excitement. During the moment, when (tension on a conclusion of "S" of the generator) will reach tension of the storage battery of value about 14,4 In, the current of a winding of excitement will stop. As soon as tension of the storage battery will go down below adjustable value, the tension regulator again closes a chain of a winding of excitement. Thus, at the expense of regulation of a current of a winding of excitement constant tension of an onboard network is supported. If the current of a winding of excitement remains to constants, with increase in frequency of rotation of the engine tension of the generator increases.
