DC Dynamo. A DC dynamo, also known as a direct current generator, produces a constant, unidirectional flow of electricity. It finds applications in numerous fields, including early power generation, electric vehicles, and portable generators. AC Dynamo. An AC dynamo, also called an alternator, generates alternating current.

Starting in the late 1880s, Thomas Edison and Nikola Tesla were embroiled in a battle now known as the War of the Currents. Edison developed direct current -- current that runs continually in a single direction, like in a battery or a fuel cell. During the early years of electricity, direct current (shorthanded as DC) was the standard

DC is constant and moves in one direction. "A simple way to visualize the difference is that, when graphed, a DC current looks like a flat line, whereas the flow of AC on a graph makes a sinusoid or wave-like pattern," says Berggren. "This is because AC changes over time in an oscillating repetition — the up curve indicates the current
"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

A simple dc generator consists of a coil of wire rotating in a magnetic field. However, it uses a split ring commutator rather than the two slip rings found in alternating current (ac) generators.
In the first practical electric generators, called dynamos, the AC was converted into DC with a commutator, a set of rotating switch contacts on the armature shaft. The commutator reversed the connection of the

AC Generator produces an Alternating Current, where the flow of electric charge periodically reverses direction. It employs a rotating coil (armature) within a magnetic field to induce changing magnetic flux and generate an alternating voltage. DC generator generates Direct Current, characterized by a unidirectional flow of electric charge.

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

The voltage and current are sinusoidal and are in phase for a simple resistance circuit. The frequencies and peak voltages of AC sources differ greatly.
The major difference between an AC Generator and a DC Generator is that the DC Generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. There are several other primary differences between AC
