Hello

1. SR-DAB has better efficiency than CLLLC or DAB? (At first glance it looks like this)

2. Is it good topology for bidirectionl DC/DC converter with Uin=400V/Uout=48V/Pout=3KW ? (We are starting new design)

3. Do you have some any technical papers like design procedure, principle of operation for this design?

4. Do you have some simulation model with control? Just something to help me get the design right. My email is: martin.supolik@a2b.sk

Hi, Martin Šupolik

1. I think the efficiency is depending on the application and system spec that you are working on. For design PMP41134 which is applied in ESS, SR DAB has better efficiency in reverse operation (from low voltage side to high voltage side) than CLLLC.

2. What is your gain range of your new design? And what is your end application? Do you have transition time requirement? If it only operates with Uin=400V/Uout=48V/Pout=3KW, both CLLLC and SR DAB are good topology to use

3. I will send the technical documents and simulation files to you

Regards,

Hello

Input voltage range is 360-430VDC.Output voltage range is 42-58VDC. We do not have strict transition time. Application is power supply for ESS. Next aplication can be charger.

SR DAB could be a good topology for your application
