    In LLC the switching frequency will be in the right of the resonance frequency or above the resonance frequency, so we will be in the inductive region, if we let the LLC operate in the left of the resonance frequency , it will be in capacitive region and this will cause problem and may be the 2 switch conduct in the same time, can some one please explain why this happen
