DC/Direct current generator
Direct current generation can be quite similar to AC generation, in that the electromagnetic generation of energy still requires all the same essential components. However, direct current is also generated by photovoltaic cells and batteries. Direct current generator are rare in major power plants due to the prevalent use of alternating current over direct current in transmission lines. Direct current generation is therefore limited mainly to small-scale generators.
The basic layout of a traditional direct current generator is quite similar to that of an alternating current generator, except for the addition of a split-ring commutator . Each arm of the armature is connected to a half of the split-ring, and this ring rotates with the armature.
