A magnetic material normally has a tendency to generate eddy current in response to a rising magnetic frequency.Īs the frequency is increased, eddy current also increases causing heating of the material and increase in coil impedance, which leads to further switching losses.įerrite cores, due to to their high magnetic permeability are able to work more efficiently with higher frequencies, due to lower eddy currents and lower switching losses. Meaning, when subjected to a magnetic field, ferrite material is able to achieve a very high degree of magnetization, better than all other forms of magnetic material.Ī higher magnetic permeability means, lower amount of eddy current and lower switching losses. In contrast, ferrite cores possess very high magnetic permeability. It is because in iron core transformers, the iron material has much inferior magnetic permeability than ferrite material. Right, it is to achieve higher efficiency and compactness compared to iron core power supplies, but it would be interesting to know how ferrite cores allow us to achieve this high degree of efficiency and compactness? You might have often wondered the reason behind using ferrite cores in all modern switch mode power supplies or SMPS converters. Why Ferrite Core is used in High Frequency Converters How to Calculate Ferrite Core Inverter Transformer.Why Ferrite Core is used in High Frequency Converters.bushing, partial discharge or DGA sensors. Furthermore, based on the digital twin, for highly developed applications, additional advanced sensors can be used on the asset, e.g. With a full temperature view, the current heat status can always be checked, a life consumption view gives indications on the residual lifetime of the asset. Data submission can be done via GSM as well as Ethernet-connection without the need of a secondary IT infrastructure.Ī Sensformer® Advanced is equipped with a digital twin, which simulates the behavior of the physical asset in real time and thus creates a completely new type of experience and value-add applications: An active overload manager allows Sensformer® Advanced operators to manage temporary overloads without compromising on lifetime. To step into the world of digitalized transformers, you simply add a GSM-card. Now your transformers are connective!Ī Sensformer® contains the necessary sensors for entering the most important operating parameters – such as oil-level, temperature, LV winding current and GPS-positioning. Sensformer® enables you to digitize this important keystone of your grid. Transformers are a vital and decisive part of power grids – no matter if conventional or digital.
