Hi John,
Please see following e2e post regarding the EVM transformer details.

Hi John,
I believe its 16:1 turn ratio. Anyways I would recommend you to reach out to magnetics manufacturer customer-service@rencousa.com ; engineering@rencousa.com regarding the turns ratio.
They should be able to provide the accurate information.

Hi Manikanta
ok, i will contact magnetics manufacturer customer-service
and i have checked schematic, there are 2 capacitor(C7 & C8) beside half bridge of MOSFET(Q1 & Q2)
may i ask how much capacitance of resonant capacitor this half bridge LLC ? is it C8 only or C7+C8?
due to the circuit structure made me confused, i'm not sure its series resonant or parallel resonant ?
thanks a lot!
Hi John,
C7 and C8 in EVM form the split resonant capacitor of LLC. So, total resonant capacitor value would be C7+C8.
Its still a LLC resonant converter.
Please see the following e2e post for further details.
Please let me know if you have any further questions.
