Abstract
Control method and circuit for resonant converters with capacitive protection. When a resonant converter enters into a capacitive mode, a high-side switch and a low-side switch of the resonant converter are turned off. After the high-side switch and a low-side switch are turned off for N switching cycles, the high-side switch is turned on once a current sense signal flowing through a resonant inductor of the resonant converter is increased to a zero-crossing threshold during an ascent stage of the current sense signal, and the low-side switch is turned on once the current sense signal is decreased to the zero-crossing threshold during a descent stage of the current sense signal.
