Temperature Stability of soft Magnetic data of Ring inductor| GETWELL

What is the temperature stability of soft magnetic data in the toroidal inductor? Let's follow the inductor distributor to understand the working principle of soft magnetism in toroidal inductor .

When making toroidal inductor , the material selection of soft magnetic data is very important. When the inductor works, the temperature will rise gradually, so the soft magnetic data must have good temperature stability. When it comes to high temperature resistance, we have to mention the iron core data magnetic ring, this magnetic ring is used to glue the magnetic powder together and shape, the center is equivalent to a lot of small air gaps.

Toroidal inductor selection

There is an air gap in the toroidal inductor coil because the magnetism of adhesive materials such as resin is roughly the same as that of air. This means that the less ferromagnetic powder contained in the magnetic ring data, the better the temperature stability of the inductor.

But in terms of cost, the cost of iron core magnetic ring is higher than that of hollow inductor. Mn-Zn materials have special high stability data, wide temperature or wide band. If the requirement is less affected by temperature, the choice of CORE depends on the effect of temperature on the inductor, and the inductance does not change much with temperature, indicating that the temperature stability of the CORE is good.

In this paper, the temperature stability of soft magnetic data of toroidal inductor is discussed, and some views on the selection of soft magnetic data are put forward. We can choose soft magnetic data according to different needs.

Working principle of toroidal inductor

The switching power supply generally chooses the half-bridge power conversion circuit, which contains high-frequency transformer and Triode and so on. During the operation of the circuit, the transistor turns on one after another, and then generates a high-frequency pulse with a frequency of 100KH, and then reduces the voltage through a high-frequency transformer, and then outputs alternating current with a lower voltage after Z. the specific voltage value is confirmed by the turn ratio of each winding coil in the high-frequency transformer. Generally, three transformers are used, namely, the main transformer, the drive transformer and the auxiliary transformer. Each transformer has its own standard and function, so one of them is indispensable.

The above is the introduction of the temperature stability of the soft magnetic data of the toroidal inductor. if you want to know more about the toroidal inductor, please feel free to contact our inductor suppliers for advice, you will get professional help.
