This way, an accurate procedure for the determination of
high voltage high frequency transformer parameters must be
obtained to propitiate a good design of the resonant circuit.
Theoretical approaches for the determination of high
voltage high frequency transformer parameters are described
in the literature [10-12]. These approaches have some
disadvantages as:
• complexity, in most of the cases is necessary to use
finite-element analysis tools;
• the analysis is dependent of the geometric
characteristics of the transformer, insulation
material, core material and the constructive
aspects of the windings.
In this paper a practical procedure for the determination of
high voltage high frequency transformer parameters is
described. This procedure is independent of the geometric
characteristics of the transformer and the constructive aspects
of the windings. The practical procedure is applied in the
design of a switched-mode power supply with 700W output
power, 50kV output voltage and 45kHz switching frequency
