High-frequency transformer (HFT) operates using the same principles as standard transformers.
The main difference is that, as its name implies, it operates at higher frequencies, whereas most
power transformers operate at 50/60 Hz, HFT uses frequency ranges from 20 kHz to over 1MHz.
HFT uses a ferrite core due to high magnetic permeability. This type of transformers offers very
low losses and its size is significantly smaller than the conventional one. Due to this, ferrite core
transformers are used in high-frequency applications such as in Switch Mode Power Supply
(SMPS).

Objectives:XX=28, Y=7 The objective of this project is to design a (XX/Y) KVA, 220/6600 volts, high frequency (100 kHz) single-phase transformer by doing the necessary calculations to provide the following: 1. The number of turns in primary and secondary. 2. The primary and secondary currents in Amperes. 3. The detailed information about AWG Copper Magnet Wire to be winded and placed in the former for the primary and secondary windings, information about AWG, length in mm, diameter in mm, the area in mm2, resistance... etc. for both the primary and secondary. 4. The former size needed to curry the required primary and secondary coils. 5. The recommended ferrite core shape and dimensions. You may use any standard configuration such as E, EC, ETD, PQ, U, UI, UU, POT, EP, TROID, etc. Please refer to a data sheet provided by any manufacturer like MAGNETICS or TDK. 6. Draw the transformer and indicate the dimensions of the core and formers. (Please try to use Visio or any other preferred drawing software). 7. Estimate the cost of your designed transformer.
