Abstract: A system includes a first battery, a second battery, an integrated circuit, a capacitor, and an inductor. The first battery has first and second battery terminals. The second battery has a third and fourth battery terminals. The second battery terminal is coupled to the third battery terminal. The integrated circuit includes a first transistor, a second transistor, a third transistor, and a fourth transistor. The first transistor is coupled between the first battery terminal and a capacitor terminal. The second transistor is coupled between the capacitor terminal and the second battery terminal. The third transistor is coupled between the third battery terminal and an inductor terminal. The fourth transistor is coupled between the inductor terminal and the fourth battery terminal. The capacitor and the inductor are coupled in series. The capacitor is coupled to the capacitor terminal and the inductor coupled to the inductor terminal.

Abstract: An apparatus includes a charge transfer circuit, a control circuit, and a processing circuit. The charge transfer circuit has a first terminal, a second terminal, a third terminal, and a control input. The control circuit has a control output coupled to the control input. The processing circuit has a first input, a second input, and an output. The processing circuit is configured to receive a first signal at the first input and receive a second signal at the second input. The first signal represents a current through the charge transfer circuit. The second signal represents at least one of a first voltage between the first and second terminals or a second voltage between the second and third terminals. The processing circuit is also configured to provide a third signal based on the first and second signals at the output.

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.
