Abstract: A resonant converter converts a DC voltage into an output voltage. The resonant converter includes a transformer, a primary-side circuit, and a control module. The primary-side circuit receives the DC voltage, and includes a resonant circuit. The resonant circuit is coupled to the primary-side winding to form a resonant module. The control module is coupled to the primary-side circuit, and controls the primary-side circuit to convert the DC voltage so as to generate a winding voltage at two ends of the resonant module. When the control module detects that an output current of the resonant converter is in a current interval between a predetermined current and a rated current, the control module adjusts a duty cycle of the winding voltage with a variation.
