llc

Hello I am designing LLC Half-Bridge converter. Pout = 500W Out= 12V Vin=390V Fr = 80kHz Lr = 30 uH, Cr = 120nF , Lp = 190uH The converter is working always above resonant frequency. The oscillographs you see are measured in 200W Pout. As you can see the green channel is Lr current, red channel...

Hi guys, I'm currently learning about the LLC converter. But a few questions popped up. Q1: Uncertainties about the body diode Primary Side Some sources state, that the LLC to be able to gurantee ZVS operation an intrinsic body diode is necessary. Resonant inductor current must be high enough...
