Text c ac generator (alternator)
In the early 1960s, the demands on a car's electrical system had become so great that the DC generator could not handle them. So, the alternator was developed. It is much more efficient than the DC generator, and is able to provide a great deal of current, even at engine idling speed.
Like a DC generator, an alternator relies on the relative movement of a wire loop and a magnet to create current. But there are some major differences.
In an alternator, the magnet rotates, while the wire loops are stationary. To provide electricity to make the magnet work, an alternator uses carbon brushes, operating against continuous slip rings — they're not segmented like a commutator. This means the magnet gets a constant supply of battery voltage, no matter what position it’s rotated to. The wire loops are arranged in the generator housing so the rotating magnetic field cuts through each loop in turn.
But, because the rotating magnet has north and south poles like any other magnet, each wire loop gets a shot of “north” followed by a shot of “south” on each revolution. Remember that the flow direction of induced current depends on the direction of the magnetic field or movement. So, each loop gets current induced in one direction, then the other, producing alternating current. But auto electrical systems operate on DC, not AC.
The breakthrough that made alternators practical for use in DC electrical systems is an electronic device called a diode. It permits current to flow in one direction only. In an alternator, alternating current passes through a set of diodes that change it into a series of one-way current pulses separated by intervals of no current flow. Because these pulses happen so rapidly, the output appears to be a constant stream of DC current.
Although the alternator originally was learned with a mechanical voltage regulator, engineers soon found a way to transistorize regulator functions. This led to the development of the all-electronic voltage regulator. In time, its size was reduced to the point that it could be installed inside the alternator housing. It has no moving parts and is not serviceable or adjustable in any way. If the voltage regulator becomes defective, you re-place it. However, its electronic components are extremely reliable, so replacement isn't often needed.
