Abstract
This paper presents a design and fabrication of a high
frequency transformer for 5 kW power rating. Within an
operating frequency of 25 kHz, a MnZn P type core has
been utilized. Two set of E-E geometry cores had to be
stacked in order to achieve rhe calculated 64.14 cm4 of
the W^Ac volume. Test and validation of the designed
shows that the prototype designed tansformer had
proven to be very compact, higher fill factor, smaller in
size, lighter in weight if compared to other winding
approaches which utilizing copper round wires. The
measured overall losses of the transformer itself were
remain below the expected value of 32.974 W. The
efficiency of the transformer was found to be at 93%
average. Overall test results also show that the design
and implementation of this high frequency power
transformer is applicable especially fo renewable energy
system..
