The demand for the miniaturization and higher efficiency of transformers and reactors has been increasing. However, to meet this demand, many complex phenomena need to be solved. For example, adopting a higher frequency for the size reduction causes the losses to increase due to the skin effects. Also, reducing the isolation space causes the heat to be trapped inside.

Using the electromagnetic CAE allows you to investigate the cause of losses visually, and take a necessary measure. You can also parameterize the geometry and quickly calculate the characteristics of a transformer, reducing the number of prototypes.
