<p>Protection system for a resonant converter with synchronous rectification. The resonant converter is comprising a control system for providing a control signal to first and second rectifier switches (Sr1, Sr2) of the converter. The protection system comprises a first sensing means (1) for measuring the voltage over the first rectifier switch (Sr1) and a second sensing means (2) for measuring the voltage over the second rectifier switch (Sr2); and an override circuit (OC1, OC2) for each of the first and second rectifier switches (Sr1, Sr2), for overriding the control signal from the control system when the measured voltage over the opposite rectifier switch (Sr1, Sr2) is below a predetermined threshold value Vref.</p> |
