Analytical Calculation of Resistance, Leakage Inductance and Parasitic Capacitance for High Frequency Transformer

摘要

The design of a high-frequency transfokmer, 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.
