Hi Every one,

I have a query regarding the transformer (ATWPPQ656264A200P) winding that is used in the reference design of the 22kW Bi-directional High-Efficiency DC/DC Converter "https://www.wolfspeed.com/crd-22dd12n/.

What should be a way of winding placement on the bobbin,

1. Option:

Half of the high-voltage winding

Full low-voltage winding

Half of the high-voltage winding

or

2. Option:

Full high-voltage winding

Full low-voltage winding

With proper Isolation between windings and core as per standards (in both cases)

Please suggested which option must be preferable and why?

Thanks
