The use of Ac generators is a very widespread feature in many applications such as, In cars, there they are known as alternators power generation from wind turbines power generation from hydroelectric dams Ac generators have usually many significant advantages over given DC Generators:

• The design is simple.
• Maintenance costs are low.
• Loss is minimal
• The size of the machines is consistent.
• Ac generators are cheaper to produce

It is easy to go up and down the power generated by an Ac generator with the help of transformers

These are the definitions that Ac generators are the most advanced technology in many systems.
