Analytical Calculation of Resistance, Leakage Inductance and Parasitic Capacitance for High Frequency Transformer
Journal of Magnetics, Volume 25, Number 1, 31 Mar 2020, Pages 86-91
Abstract
The design of a high-frequency transformer, which is the main component of a DC/DC converter, is very
important. In the case of a DC transmission system, such as HVDC, the transformer should use high power
and high frequency, but there are few studies in this category. Therefore, this study examined the design of a
high frequency transformer. When designing the transformer covered in this paper, it is necessary to consider
the frequency components differently from a traditional transformer design. Therefore, winding resistance,
leakage inductance, and parasitic capacitance were calculated according to the frequency change, and finite element
method (FEM) analysis and comparative analysis were conducted for validation.
