Hi David,
to me looks that the system is implementing a single-phase AC/DC converter. You could propose the following reference design for example https://www.ti.com/tool/PMP23069
Related to the isolated DCDC conversion you can propose the following:…
Hello Feng,
LM5170 is buck in one direction and boost in the other. This means it cannot fill your need of buck and boost in the same direction. This is a pitty.as it is easily stackable.
Maybe you might think about a resonant converter, similar to this…
Part Number: TIDA-010062 Other Parts Discussed in Thread: PMP20978 , Hi,
We are aiming at 96+% efficiency for PFC+LLC at 750W.
The design has tight spacing requirements ~ 45W/in3 for the inner room.
The casing is designed to dissipate 30W with a 30~35…
Hello,
I found a 1 kW reference design in the TI library that you may find interesting that uses the UCD3138 in a LLC configuration at the following link.
