A Brief Discussion on the Working Principle, Function, and Practical Application Advantages of Adjustable Inductors 1

Adjustable inductor is an electronic component that can adjust its inductance value, and it has a wide range of applications and many advantages. Below, I will briefly introduce the working principle, function, and practical application advantages of adjustable inductors.  diode

1. Working principle:

Adjustable inductors are typically composed of coils, iron cores, and adjustable inductor cores. By adjusting the position or shape of the inductor core, the self inductance value in the coil can be changed. Specifically, as the magnetic coupling between the inductor core and the coil increases, the inductance value will also increase; On the contrary, when the coupling decreases, the inductance value will decrease. This adjustment mechanism can be achieved through knobs, handles, or voltage control.diode

2. Function:

Adjustable inductors play an important role in various circuits. It mainly includes the following aspects:

a. Frequency regulation: Adjustable inductors can adjust the frequency response characteristics of circuits, such as in radio receivers used to regulate the frequency of inductor resonant circuits.

b. Energy storage and energy transfer: Adjustable inductors can store electrical energy and transfer it to other circuits when needed, such as in power supplies and DC/DC converters.diode

c. Filtering and interference suppression: Adjustable inductors can be combined with other components (such as DG409DJ capacitors) for filtering circuits to suppress interference and noise.
