Hello: I would like to ask why the IRS2795 used in my LLC switching power supply automatically stops working after running for a period of time. Does it have anything to do with the parameter selection of the resonant network? What causes this situation? Resonant network parameters are lr=100uH, cr=22nF, lm=500uH. Thank you!

I added two 27K parallel fake loads to the output. Is this basically equivalent to no load?

Did this cause the work to stop working after a while?
