Introduction to Fixed Inductors

Fixed inductors, also referred to as chokes, are essential parts of electrical circuits and are generally used to store energy. They are used extensively in electronic equipment, from antennas and RF transmitters to power electronics.

What is a Fixed Inductor?

A fixed inductor is a small electronic component that stores energy in an inductive loop. When a current is applied, the inductor generates an electromagnetic field that stores energy. When the current is stopped, the energy stored in the inductor’s electromagnetic field is released. This type of inductor is commonly used in inductors, transformers, resonant circuits, and various power supplies.

Application Fields

Fixed inductors are used in a variety of applications to help store energy. The most common applications of fixed inductors include

• Power supplies
• Switching power supplies
• High-frequency power supplies
• RF amplifiers
• Filtering circuits
• Inverters
• DC-DC converters
• Antennas

Working Principle

The working principle of a fixed inductor is quite simple. It requires just two wires to operate. When a current is applied to the inductor, it creates an electromagnetic field that stores energy. When the current is stopped, the energy stored in the electromagnetic field is released. This is known as inductive kickback where energy is released quickly and is ideal for high-frequency circuits.

Advantages of Fixed Inductors

The use of fixed inductors offers several advantages, such as:

• High energy storage capacity
• Good efficiency
• Low power dissipation
• High accuracy
• Compact design
• Easy installation
• Low cost

Conclusion

Fixed inductors are an essential component in many electronic circuits. They offer several advantages including high energy storage capacity, good efficiency, low power dissipation, high accuracy, compact design, easy installation and low cost. They are used in a variety of applications in the fields of power supplies, RF amplifiers, filtering circuits, inverters, and DC-DC converters.
