Original Abstract Submitted
A driver circuit for a resonant converter includes an analog zero current comparator configured to generate a first control signal indicating when a resonant current of the resonant converter changes sign, a triangular wave generator circuit configured to provide at output a triangular signal, and a comparison circuit configured to generate a second control signal indicating whether the triangular signal reaches a reference threshold. The driver circuit is configured to drive a high-side and a low-side electronic switch via respective drive signals during a first and a second consecutive switching semi-period, wherein each of the first and the second switching semi-period ends when the comparison circuit indicates that the triangular signal has reached the reference threshold.
