Difference between AC and DC generator


In this article we will discuss about the measure difference between AC and DC generator. We will discuss about the construction and working principle difference between both . Basicaly ac and dc generator both convert mechanical power into electrical power and work on principle of faraday law of electromagnetic induction.

Difference between AC and DC generator

Difference between ac and dc generator, difference between dc and ac generator

                    AC generator

                                DC generator

1.  In this type generator , the current is flow through a coil
In this type generator, The current is not flow through the coil.
2. It convert mechanical power into AC electrical power , it  work on principle of electromagnetic induction
It convert mechanical power into DC electrical power, it is also work on principle of electromagnetic induction.
3. AC generator generates AC electrical power.
DC generator generates dc electrical power.
It have two commutators .
It have only one commutator.
4. The AC generator produces variable output voltage in term of amplitude and time. For some instance, it have a normal frequency of 60HZ . In India it is 50HZ.
The DC generator produces constant output voltage in term of amplitude and time. Its output frequency is 0HZ.
5. It is used to power for smaller motors and electrical appliances at home. These appliances that can be operated using ac generator including juicing machine, electrical mixtures, and food mixture
It is used for functional in supplying power to heavy motors. As like off-grid batteries, rely and other electronic equipment.
6. It is less efficient for charging purpose; simply we can say that it is less reliable and efficient for charging of various devices, as like batteries, mobile.
It is more efficient for charging purpose; it is more reliable and efficient for charging various device.
7. AC generator could not produce dc power
DC generator could produce ac power
8. A AC generator does not require a special mechanism to take AC power from generator.
It is the measure difference between AC and DC generator
A dc generator requires a special mechanism to provide a DC output. it can be done mechanically with an electronically with a rectifier or commutator.  Commutator is a device which takes input in AC and gives output in DC.  
9.  In AC generator uses slip ring and brush. Here does not use of commutator
In DC generator uses commutator and brushes.
It is also a constructional difference between ac and dc generator.

So it is some measure difference between ac and dc generator. If you will find any mistake please comment below.
