Abstract: A controller circuit is configured to receive a measurement signal representing a power converter state and receive a control signal representing a power converter resonant period. Based on the power converter state and the power converter resonant period, the controller circuit determines for a switching cycle: a charging interval, a first dead time interval, a discharging interval, and a second dead time interval. The first dead time interval is after the charging interval. The discharging interval is after the first dead time interval. The second dead time interval is after the discharging interval. The controller circuit provides a first drive signal and a second drive signal based on the charging interval, the first dead time interval, the discharging interval, and the second dead time interval.
