It is the combination of transformer winding inductance, uncoupled or leakage inductance and a series capacitance hence LLC.
The LLC converter is a DC/DC converter based on a resonant circuit which allows soft-switching operation. The LLC resonant circuit reduces switching loss through zero-voltage switching (ZVS). Unlike the SLR converter, the LLC converter can keep the output voltage regulated even under light load condition.
