Abstract

A controller for a resonant converter. If a measured current signal is greater than an upper-low-load-current-threshold, then the controller sets an upper-voltage-threshold-value based on the measured current signal. If the measured current signal is not greater than the upper-low-load-current-threshold, then the controller sets the upper-voltage-threshold-value based on the power setting signal but independent of the measured current signal. If the measured current signal is less than a lower-low-load-current-threshold, then the controller sets a lower-voltage-threshold-value based on the measured current signal. If the measured current signal is not less than the lower-low-load-current-threshold, then the controller sets the lower-voltage-threshold-value based on the power setting signal but independent of the measured current signal. In response to a measured voltage signal exceeding the upper-voltage-threshold-value, the controller opens the first switch and closes the second switch. In response to the measured voltage signal dropping below a lower-voltage-threshold-value, the controller opens the second switch and closes the first switch.
