What Are The Requirements For High Frequency
Power Transformers? Miracle Electronics
High frequency transformers can work efficiently
only if two important conditions are fulfilled
reliability and electromagnetic compatibility.
Reliability has always been paid attention to,
while electromagnetic compatibility has come into
focus only in recent years because of the
increasing awareness towards environmental
protection. Reliability can be defined by the
specific conditions of usage on which the high
frequency power transformers can normally work.
The temperature in which the transformer works is
one of the very important factors to be
considered. For some soft magnetic materials, the
Curie point is very low, which is why they are
very sensitive to temperature. One such example
is manganese zinc sift ferrite that has a very
low Curie point, which is why its working
temperature is very limited.

High frequency transformers are used to complete
many functions, out of which the power
transmission is of high importance. For power
transmission, the transmission mode of the
transformer power, the voltage applied to the
primary winding, and the magnetic flux in the
magnetic core changes induce the secondary
winding voltage, which leads the electrical power
from the primary to the secondary. In this power
transmission process, the magnetic core
is divided into one-way and two-way magnetic flux
changes. In one-way change, the flux density
changes from the maximum value to the residual
flux density. Let us suppose that the maximum
value is X, the residual flux density is Y,
and the flux density change value is Z. Then,
Z X Y. In case of two-way change, the mode of
operation varies from X to X, or from X to
X, and in this case, Z 2X. Whether it is
one-way or two-way, the transformer power
transmission mode is not directly related to the
core permeability. For inductor power
transmission mode, the primary winding input
power leads to core excitation, which then leads
to magnetic energy storage, and then induces
secondary winding voltage by demagnetization,
which ultimately releases power to the load. The
transmission power is determined by the
inductance core energy storage, which is in turn
determined by the inductance of the primary
winding. However, inductance and magnetic
permeability of the core, and energy storage are
not directly related to the magnetic flux
density. Since the power transformer modes are
different, the required core parameters are also
different. Also, the high frequency power
transformer design, material core, and choice of
parameters are very important considerations. If
