Hello,

Some LLC resonant converters use an “integrated” transformer (transformer incorporating high leakage inductance), whereas others use a transformer and a separate resonant inductor.

Do you know what is the typical difference in price of these two types of transformer?

I would imagine that the “integrated” transformer , with its special dual-sectioned bobbin, would be at least twice the price of a non-integrated transformer?

-Also, surely when the assembly staff have wound the “integrated” transformers, they then must test them, and testing an “integrated” transformer must be a much longer and more labour intensive, and therefore more expensive task , than testing a non-integrated transformer?
