Abstract
A resonant power converter includes: a first transistor and a second transistor, configured to form a half-bridge circuit; a resonant circuit including a resonant inductor, a primary winding of a transformer, and a resonant capacitor, which are serially coupled to each other, and wherein the first and the second transistors are configured to switch the resonant circuit to generate a resonant current for converting an input voltage into an output voltage; and a conversion control circuit configured to generate a ramp signal based on the resonant current, and to generate a first drive signal and a second drive signal based on the ramp signal and a compensation signal related to the output voltage. The first drive signal and the second drive signal are respectively used to control the first transistor and the second transistor. During a signal period of the ramp signal, the ramp signal monotonically increases or monotonically decreases.
