Automobile Alternator


Automobile alternators are used to supply current to automobile electrical circuits when they are in operation. In addition to this, the alternator also charges the automobile battery that is used to provide power to the starter motor when the engine is started.

Typically, alternators are driven by the main engine via a pulley and belt arrangement. Alternators generate alternating current (a.c.) and this is rectified to direct current (d.c.).

Automobiles are usually operated on 12 V d.c. or 24 V d.c. circuits because low voltage and high current is required to start the automobile engine. Circuits supplied by the alternator include the head lights, interior lighting, engine management system, multimedia system and electric windows (to name a few).

There is a tendency for more and more items within automobiles to be managed by electronics and this has increased the importance of the electrical system reliability.
