Abstract:
The present invention provides a control circuit of an LLC resonant converter including a minimum switching frequency variable circuit of varying a minimum switching frequency corresponding to an AC input voltage of the LLC resonant converter; and a first pulse signal generating unit and a second pulse signal generating unit to generate a first pulse signal and a second pulse signal based on a switching frequency limited by the minimum switching frequency variable circuit.
