I am working on full-bridge CLLC, and the waveform I got is quite weird.
Is there anyone who has such kind of experience?

Thanks for your information but my cap wasn't hot. The resonant inductor in series with the transformer is hot.Of course your resonant caps get hot they have a lot of current and a lot of AC voltage, what is the DF for your cap ? what is the peak DC & AC voltage rating at the frequency you are using ?
Watts ( heat ) in the res cap = Vac x Iac x DF, so for 100Vac and 5A ac and DF = 1% the heat will be 5W
quite a lot for a cap that is not designed for an heavy duty AC application at higher frequencies ....
So - look at the data sheet and do the calcs ....
Yes, the peak of magnetizing current is about 13.4A. Do you think it contributes to resonate components heating?Is chanel 2 inverted ?
also you seem to be running a lot of magnetising current - looking at the purple waveform
