In this article, you will learn about what is DC Power Generators and the types of methods used for generating DC power.
In power generation, most of the electrical generations are based on producing three-phase alternating current.
You may have heard a lot about AC generators, which use widely for domestic purposes.
Large industries also tend to use these AC three-phase power. But some industries use direct current because of its unique features.
But some generators use DC for sophisticated purposes.
For example, Tractions, chemical plants, and metallurgical plants. Alternative Current (AC) converts into Direct Current (DC) using converters and other devices in these industries.
Before we move in to advance first, we will check out different types of dc generators in the industry.
Types of DC Power Generators
There are a lot of power generators used in the electrical industry for different purposes.
DC power generators are subdivided into two main categories on their method of excitation.
- Separately Excited Generators
- Self Excited Generators
Here’s the deal:
Separately Excited DC Generators
In these DC generators, the field wind magnet is used to be energized by an external DC.
This means basically the generator field coils were getting powerup by using an independent power source.
The major advantage of this method is that the output voltage can easily be controlled. And the ability to control a wide range too.
Self Excited DC Generators
The field coils are self-excited in this type of generator, so small magnetization effect the generator into the rotor, and the induced emf in armature winding get weak, s
O a magnetic field created. In this type of DC generators, the field winding magnets are energized using the Direct current produce by itself.
These self-excited DC power Generators can further be classified into three main categories according to the field winding connection, such as.
- Shunt Wound Generators (In these types of dc generators, the field wind is connected with parallel to armature conductors.)
- Series Wound Generators (In here, the field windings are joined in series with armature conductors)
- Compound Wound Generators
This type of generator has unique advantages over other generators, and most of these generators can perform precise controlling.
I hope that you have got some basic understanding of what are DC power generators and their types.
Application of DC Generators:
DC power generators are mainly used for self-control power plants such as airplanes, Vehicle lighting, and automobiles industries.
Unlike AC generators, most of the DC type generators are much stable to use for arc lamps.
Benefits of DC Generators:
One of the most important benefits of a DC generator is high reliability, which can be used for industries where reliability is considered a prime factor.
Unlike AC generators, most of the DC generators required low maintenances.
The design of these types of generators works at a low speed, so its lifetime is higher than the other types of generators.
Conclusion:
I hope that by reading this article, you have got an idea about what is this DC power generators, different types of generators, and their application.
