Abstract: One example includes an apparatus that includes an insulating layer and an electrically conductive layer on the insulating layer. The conductive layer includes a plurality of electrically isolated and conductive regions. A first switch is on a first of the conductive regions, and the first switch has a first terminal and a second terminal. A second switch is on a second of the conductive regions, and the second switch has a third terminal and fourth terminal. A passive component has a fifth terminal and a sixth terminal. The first and third terminals are coupled to the first conductive region. The fourth and sixth terminals are coupled to the second conductive region. The second and fifth terminals are coupled to a third of the conductive regions.

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.
