Difference Between AC and DC Generator
Till now we have learned above what is called Ac and Dc Generator. If you have read all the things given above carefully, then you must have understood well about the difference between AC and DC Generator.
If you still have any confusion in understanding what is AC and DC Generator and what is the difference between them, then now we are going to tell you some important differences between them below.
Parameters |
AC Generator |
DC Generator |
---|---|---|
Output Power |
It generates AC electrical power. |
It produces DC electrical power |
Rings |
AC generators have close slip-rings. |
Dc generators have split-ring commutators. |
Current induction |
Its output current can be induced in the rotor or stator |
Its output current is induced in the rotor only |
Direction of Current |
The electric current reverses direction from time to time. |
Electric current flows in only one direction. |
Commutators |
AC generators do not have commutators. |
DC generators have commutators due to which current flows in only one direction. |
Distribution and Transmission |
Distribution of output in AC generator is easy. |
It is difficult to distribute output in a DC generator. |
Efficiency |
AC generators are very efficient because energy losses are low. |
DC generators are less efficient due to sparking and other losses such as copper, eddy current, mechanical and hysteresis losses. |
Maintenance |
Requires very less. |
Requires very less Requires very less |
Types |
Rotating armature, Rotating field Single-phase, Three-phase |
Permanent magnet, Separately excited, Self-excited |
Voltage Distribution |
Transformers are used to distribute AC voltage. |
Transformers are not used to distribute DC voltage. |
Voltage Level |
AC generators are useful for generating very high voltages |
Dc generator is used to generate low voltage |

Difference Between AC and DC Generator
An electrical machine that converts mechanical energy input into electrical energy output is called a generator or electrical generator. There are two types of generators, AC Generators and DC Generator. An AC generator has an electromagnet while a DC generator has a permanent magnet. AC generators have commutators while DC generators have slip rings.
In this article, we will learn what is AC and DC Generators and the Difference Between AC and DC Generator. There are some important differences between AC and DC Generator which we will understand below through the difference table but before that let us understand better what is AC and DC Generator.
