Transformer part number for LLC converter?

Question

Electronics

Perhaps I’m looking badly, and I’m not asking there, but are there any ready-made transformers for LLC converters with n 2:1:1 or so that you can buy? A la Wurth or Coilcraft. It is necessary to get 150V output from 380V after PFC. If anyone knows specific names, I will be grateful. Or is there no way out and you have to wind it yourself?

Answer 1

are there ready made transformers for LLC converters with n 2:1:1 or so that can be bought?

Most likely, there are such (because the variety of hankies is extremely large), but on your way they can only meet by chance, just because of the variety. You can buy only standardized products created for typical tasks (a vivid example is 50-Hz transformers of the TA, TN, TAN, Chamber of Commerce and Industry series, etc.). In other cases (and the vast majority of them), manufacturers are forced to wind themselves, and only occasionally put their winding products on sale as spare parts for repair work, and often without publishing accurate technical data.

Or is there no way out and you have to wind it yourself?

Exactly. But I believe that there should be services that make inductive components to order (similar to how you can order printed circuit boards). I have never used one myself, because I know how to do these things myself.

But most likely not: too rare a combination. Well, the power is not indicated.
Wind up yourself. If the party, there are firms that wind to order.
