2. Alternator (automotive) - Wikipedia

   en.wikipedia.org/wiki/Alternator_(automotive)

   Alternator (silver) mounted on a V8 engine Alternator voltage regulator (brushes are worn out) An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.

3. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   A brushless alternator is composed of two alternators built end-to-end on one shaft. Until 1966, alternators used brushes with rotating field. [21] With the advancement in semiconductor technology, brushless alternators are possible. Smaller brushless alternators may look like one unit, but the two parts are readily identifiable in the large ...

4. Compensated pulsed alternator - Wikipedia

   en.wikipedia.org/wiki/Compensated_pulsed_alternator

   A compensated pulsed alternator, [1] also known by the portmanteau compulsator, is a form of power supply. As the name suggests, it is an alternator that is "compensated" (see below) to make it better at delivering pulses of electrical energy than a normal alternator.

5. 42-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/42-volt_electrical_system

   Six-cell lead-acid batteries produce around 12.6 volts while discharging, and their corresponding automotive alternators are designed to produce 13.5 to 14.5 volts during charging. [ 1 ] 42 volts is an approximation of the output of the new standard's charging system. [ 2 ]

6. Voltage regulator - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulator

   Early automobile generators and alternators had a mechanical voltage regulator using one, two, or three relays and various resistors to stabilize the generator's output at slightly more than 6.7 or 13.4 V to maintain the battery as independently of the engine's rpm or the varying load on the vehicle's electrical system as possible.

7. Dynamo - Wikipedia

   en.wikipedia.org/wiki/Dynamo

   "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
