Resonant converter with capacitive mode control and associated control method
A control circuit used for controlling a resonant converter. The control circuit has a setting capacitor, N up thresholds and N low thresholds. If the resonant converter operates in the inductive mode, a setting voltage signal across the setting capacitor is respectively compared with the largest one of the N up thresholds and the smallest one of the N low thresholds in each operation cycle to generate a high-side control signal and a low-side control signal for controlling a high-side switch and a low-side switch of the resonant converter. If the resonant converter enters into the capacitive mode, the setting voltage signal is respectively compared with each of the N up thresholds and each of the N low thresholds operation cycle by operation cycle to generate the high-side control signal and the low-side control signal.
