Transformers have complex structures in which coils share magnetic paths; the transformer coupling rate and losses are heavily dependent on materials and geometry. This makes it difficult to accurately evaluate transformer properties during the stages prior to a trial production. Actual development is usually conducted by performing a trial production relying on the rule of thumb to determine the structure.
However, in the simulation, it is harder for simplified models to achieve sufficient accuracy in higher frequency, which often results in the necessity of a trial production to perform satisfactory design verification.
During this seminar, modeling effects will be verified through the comparison between a magnetic analysis performed on a transformer and measured values.
