==Original Abstract Submitted==

A controller for a resonant converter. The controller is configured to: compare a measured current signal with a positive current threshold; compare the measured current signal with a negative current threshold; and set a power reduction mode as active if either or both: the measured current signal is less than the positive current threshold at the end of the preceding high-side switch half cycle; and the measured current signal is greater than the negative current threshold at the end of the preceding low-side switch half cycle. While the power reduction mode is active: the controller gradually decreases the value of a reduced power signal. While the power reduction mode is inactive: the controller gradually increases the value of the reduced power signal. the controller sets an upper voltage threshold value and a lower voltage threshold value based on the lower of: i) the reduced power signal; and ii) a power setting signal.
