Abstract
A control device for a resonant converter includes a first circuit structured to rectify a signal indicating the current circulating in the primary winding, a second circuit adapted to integrate at least the rectified signal and structured to generate at least a control signal of the switching circuit according to the integrated signal, and a third circuit adapted to send a reset command to the second circuit so as to inhibit the operation over a time period between the instant when the integrated signal reaches or exceeds a first signal and the instant of the next zero crossing of the signal, indicating the current circulating in the primary winding.
