Other Parts Discussed in Thread: UCC24624
Hi,
I have a correctly working 72V to 14.5V LLC convertor design with UCC256402. Here is the output section of it.
Its output rectifiers get verry hot. So I added synchronous rectification to it with UCC24624 controller. Here are the schematic sections of it.
This design not working as expected. When I use diodes instead of synchronous rectification for my new PCB with some trace cuttings and previous diode direction, It works properly.
What is the issue here.
Is there a way to select diode directions with transformer dot convention?
Here I added my transformer data for your reference.
