Difference Between AC and DC Generator

Difference between AC and DC Generator – FAQs

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.
