This paper presents a modeling design and analysis
of a high-frequency transformer (HFT) of flyback PEmag
simulation operating in critical conduction which could be used
for a wireless charging circuit for an electric vehicle (EV) from
a pipeline through the electromagnetic field of high voltage
transmission lines for mitigation and avoiding AC corrosion.
Discriminating a transformer core and wire sizing becomes a
very important criterion for an efficient operation for current,
voltage, losses of core, and primary and secondary windings.
The high-frequency magnetic core and the winding method of
magnetic components have been selected for suitable
parameters which included 25, 50, 100, and 200 switching
high-frequency transformers. The feasibility of the design
scheme is verified and calculated by several software program
implementation results. The following overview provides a loss
study of the flyback high-frequency transformer including
losses of copper (both DC and AC winding loss) and core loss
calculations as well. This HFT is used in contact with a design
circuit of wireless power transfer of charging from a highvoltage
transmission line. The wireless power transfer offers a
new path to energy acquisition for electric-driven devices such
as electric vehicles. The model is entered into a software
application for electromagnetic and transformer calculations to
prevent instability problems during modeling simulation
processes. |
