Thanks for your answer, I am using this driver, please check the attached picture, by the way, I am using the Mosfet UJ3C065080K3SWhat are you using as MOSFET drivers? It looks like coupling through the gate-drain capacitance, suggesting that the gate drive impedance is too high.
Thanks for your reply, it's just a Full bridge CLLC circuit, and the Vgs of the high side MOSFET get induced and self-turn-on. Would you please have a look at the attached picture I posed earlier?What weirdness are you concerned about?
Show the complete circuit schematic of what you have.

Sorry for not drawing in detail, Please check this picture. Thank youDoesn't help much.
This seems to be game of 20 questions.
A schematic shows the complete circuit.
What are all the blocks with nothing to tell what's inside?
yeah, i use isolated power supply 15v for each MOSFET driver, according to the driver’s datasheet i posted earlier its max current 3A
