Dec 5, 2023 · The figure shows that Type A transformer depicts low core losses as compared to the other two transformers both at light and heavy load conditions. At 400 V, Type A transformer has core losses of nearly 6 W for both heavy and light load while the ferrite and Type B transformer’s core losses are comparatively higher 7 W and 20 W, respectively.
Abstract: Typically, the core loss of the high-frequency (HF) transformers is considered constant regardless of the load condition on the secondary side. This paper indicates that the various load conditions can affect the core loss in HF transformers due to the variation of winding parasitics elements and subsequently the transformer's ...

This two-part paper presents an overview of core loss computations performed in both time and frequency domains in order to evaluate their behavior in single phase transformers with different core ...
Feb 12, 2019 · In this paper, we propose a simple and practical technique, which precisely depicts the actual power loss in a high frequency ferrite core transformer. With this technique various ferrite cores can be characterized for their hysteresis losses at varying flux densities and frequencies.
