Which transformer is used for high-frequency application?
Ferrite core power transformers are widely used in switched-mode power supplies (SMPSs). The powder core enables high-frequency operation, and hence much smaller size-to-power ratio than laminated-iron transformers.
What are high-frequency transformers used for?
These transformers are designed to handle up to 15,000 volts safely and accurately, converting high voltage and current levels between coils by magnetic induction. High Voltage, High Frequency Transformers are relied on for applications ranging from power supplies to laser equipment and particle accelerators.
Why ferrites are used in high-frequency communication?
Since they are metals, they have low electrical resistance and cause a large amount of heat-generation loss due to eddy current loss under a kilohertz, megahertz, or higher-frequency AC magnetic field. Thus, ferrite (soft ferrite) gained attention as a high-frequency soft magnetic material (invented in 1930).
Why are ferrite cores used in a transformer?
In conjunction with the increased use of GaN semiconductor, which can operate a high frequency, higher frequencies for switching power supplies have become feasible. Ferrite materials are used in transformer products, but core loss (iron loss) varies greatly depending on the driving frequency, and they are key components in transformer design.
What are the features of high frequency ferrite material?
This article presents information on the features of PC200 material, which was developed by using GaN, and key points concerning its use. TDK’s Mn-Zn ferrite cores compatible with high frequency support mass production of PC95 material.

Which is ferrite material has a low loss?
PC200 is a ferrite material with low loss at frequencies from 700kHz to 4MHz and maximum electric power conversion capacity at 1.8MHz to approximately 2MHz.
