Fixed Inductors

Fixed inductors, also known as chokes, are used to store and release energy in electric circuits. They consist of one or more loops of wire that are wound in the shape of a coil. The basic principle of a fixed inductor is that when a current passes through the coil, a magnetic field is created around it. This magnetic field stores the energy, and when the current stops, the magnetic field dissipates, releasing the energy. A fixed inductor can have different shapes, but the principle is always the same.

Application Field

Fixed inductors are widely used in many electronic applications, such as power supplies, power amplifiers, audio systems, filter circuits, motion control, and communications. In power supplies, fixed inductors are used to create a smooth, large current flow, providing a reliable power source. In amplifiers, the inductor creates a high-impedance path, which allows for the amplification of low-level signals. In filter circuits, inductors can be used to filter out unwanted frequencies, allowing only certain frequencies to be passed through. In motion control systems, inductors can be used to create a constant magnetic field, helping to generate motion. In communications systems, fixed inductors are used to create noise-free signals.

Working Principle

The basic principle of a fixed inductor is based on Faraday’s Law. Faraday’s Law states that when a changing current passes through a conductor, a magnetic flux is created around the conductor. This magnetic flux induce an electromotive force, or EMF, in said conductor. This EMF is the electrical energy stored in a fixed inductor. When the current stops, the EMF dissipates, releasing the energy back into the circuit.

Fixed inductors are commonly used in circuits to filter out transient noise and to store energy for delay or timing purposes. They are also used to create an impedance path, allowing certain frequencies to pass while blocking out others. In applications such as switching power supplies, they are used to reduce any spikes or surges in the power supply, helping to maintain a constant, steady current.

Conclusion

Fixed inductors are useful components in electronic circuits, providing a reliable source of energy and filtering out transient noise. They are also used to create a high-impedance path in amplifiers and communications applications, allowing certain frequencies to pass while blocking out others. Fixed inductors are used in power supplies, filter circuits, motion control systems, and communications systems. Their basic working principle is based on Faraday’s Law, which states that when a changing current passes through a conductor, a magnetic flux is created around the conductor, inducing an electric current.
