Alternator

Electrically operated gadgets usually have batteries that can be charged to keep them operable. Automobiles are pretty much like them, only they can't be plugged in a socket for charging. What they are equipped with is an alternator, a device that converts mechanical energy to electricity.

A car alternator is engine-driven, so it starts charging your battery and powering the rest of the electrical system when you start your vehicle. It has a small pulley that lets it double the speed of the engine. This way, it can make more output than usual when the engine is set to idle. And to convert the alternating current to direct current, the alternator uses a set of rectifiers or diode bridges. It is also equipped with a three-phase winding to ensure low-ripple direct current. The construction of alternators varies according to vehicle type, production, and application. Modern alternators already have a voltage regulator to adjust alternator output. Their efficiency also varies according to their size and speed. Smaller ones can achieve as much as 50-62% while bigger ones definitely have better efficiency.

If necessary, you can replace alternator for an even better performance. Nowadays when even the most difficult-to-find auto parts can already be easily acquired, auto maintenance and upgrade are already easier and more convenient.
