Difference Between Ac And Dc Generator

7 Difference Between Ac And Dc Generator

S.NO.	Ac Generator	Dc Generator
1.	AC (alternating current) generators produce an alternating current.	DC (direct current) generators produce a direct current.
2.	AC generators use a rotating field to produce an alternating current.	DC generators use a rotating field and a commutator to produce a direct current.
3.	AC generators are typically more efficient than DC generators, as they do not require a separate power source to generate a magnetic field.	Less efficient.
4.	AC generators have a simpler construction than DC generators, as they do not require a commutator or brushes to reverse the current flow.	Complex construction than AC generators.
5.	AC generators are typically more rugged and durable than DC generators, as they do not have moving parts such as a commutator or brushes that can wear out.	Less durable, and having moving parts such as a commutator or brushes that can wear out.
6.	AC generators are typically used in power generation and transmission systems.	DC generators are used in a wider range of applications, including portable devices and electric vehicles
