Hello, I have some doubts about Infineon's 12V 3KW server POWER SUPPLY. According to the document, the DC/DC isolation converter uses 4 transformers, using half-bridge LLC for power conversion, each transformer is responsible for a quarter For all the output power, the synchronous rectifier MOS used is Rds_on 0.5mΩ, I want to seek this model and his layout.

Hi EHEVCOSHEEN,

Thanks for using Infineon Community.

This design of AC-DC was only a study done to understand the benefits of Wide band gap devices over Si devices. Also, it was concentrated only on the secondary side devices and not on the complete converter design. But, it did not progress till the schematic phase.

Comparatively, a little extensive work was done on the DC-DC part presented in page 23 of the same document and a publication was released, which again gives only the concept and some design guidelines but not the schematic directly.
