Abstract: A driving module of a resonant converter receives an enabling signal and a voltage across a switch of a secondary side, and generates a control signal for first and second switches of the secondary side. The driving module cyclically controls switches of a primary full-bridge switching stage and both switches of the secondary side. After a fixed time, the driving module turns off the low-side switch and turns on the high-side switch, waits for a rising edge of the enabling signal, waits for zero current in the secondary side switches, turns off the first switch via the control signal after a variable delay relative to the rising edge of the enabling signal, keeps the second switch on, waits for zero voltage across the first switch, switches back on the first switch via the control signal when the voltage measured across the first switch drops below a variable threshold.

Abstract: A resonant converter includes a primary switching circuit including a primary winding and upper and lower switching half-bridge circuits alternately activated during switching cycles of the resonant converter responsive to switching control signals. The switching half-bridge circuits each include a phase node to drive the primary winding. A resonance inductor is coupled to the primary winding. A secondary resonant circuit has a secondary winding magnetically coupled to the primary winding and a resonance capacitor electrically coupled to the secondary winding. A driving circuit generates the switching control signals and senses if a voltage on the phase node of one of the upper and lower switching half-bridge circuits is a negative voltage. The driving circuit adjusts the switching control signals for the switching half-bridge circuit to be activated next switching cycle by a shift time reduced each switching cycle until the negative voltage is less than a negligible under-voltage value.
