The charging system of the car
Generally, the speed ratio of automobile engine and generator is 1:2.5, that is to say, when the engine is running at 800 RPM, that is, the engine is running at idle speed, the generator can run at 2000 RPM, which is enough to make the generator emit enough electricity. And with the increase of engine speed, the generator generation voltage and current increase. To avoid overvoltage, a regulator is installed on the generator to switch on and off the excitation current. When the generator produces too much power, the excitation current is cut off and the generator stops producing power. When the voltage is reduced, the excitation current is reconnected and the generator resumes generating power.
