Alternator

Cars are powered by batteries. So, when the batteries supplies electicity to work, if you don't constantly charge the battery, the battery's voltage will go down and the engine will turn off and the car will not be able to work. Alternator is a charging system to prevent this. Alternator generates electrical power to power the battery and other electrical systems in the vehicle. In other words, as the engine is operated, AC voltage is generated due to the interaction between the rotating rotor and the stationary stator that surrounds it, and a diode is used to rectify the generated AC to DC. KEC mass-produces Alternator Diodes specialized for this.
