Continuing the discussion from HR1211 500V Application:
Hello, same inquiry as on this discussion. I also need to make 600W battery charger similar to the eval board, but my output is for 12V battery, 40Amax output. I’m new with this topology, I just want to verify, is it right that I didn’t change the PFC circuit and just change the transformer 28:2:2?
Thank you.
Other than the transformer and ensuring that all discrete parts are rated 2-3x the output voltage (in your case 2-3x 12V), then I think you should be fine.
For further reference, please see the following schematic tuned to a 12V output at 34A shown on the EVHR1211-Y-01A datasheet (page 4):
The full BOM is also in this datasheet as well (pages 5 - 9). Let me know if there are any specific questions about the schematic.
Best,
Krishan
