Patent number: 11811316Abstract: A power supply system comprises: a switched-capacitor converter, a controller, and a monitor. Via generation of control signals, the controller controls settings of switches in the switched-capacitor converter to convert a received input voltage to an output voltage that powers a load. The monitor in the power supply system at least occasionally determines an impedance associated with the switched-capacitor converter. A magnitude of the determined impedance provides an indication whether the switched-capacitor converter is operating efficiently. To ensure efficient operation of the switched-capacitor converter, based on input form the monitor, the controller adjusts the control signals controlling the switches in the switched-capacitor converter as a function of the determined impedance.Type: GrantFiled: December 20, 2018Date of Patent: November 7, 2023Assignee: Infineon Technologies Austria AGInventors: Benjamin L.
