Patent ID: 11953971
Assignee: INFINEON TECHNOLOGIES AUSTRIA AG
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. An electronic circuit, comprising:
a buffer circuit comprising a first capacitor and a second capacitor; and
a control circuit configured to operate the buffer circuit in a first operating mode or a second operating mode,
wherein the control circuit is configured to operate the buffer circuit in the first operating mode by buffering, by the first capacitor of the buffer circuit, power provided by a power source and received by a load,
wherein the control circuit is configured to operate the buffer circuit in the second operating mode by connecting the second capacitor of the buffer circuit in series with the first capacitor to form a capacitor series circuit, supplying power to the load by the capacitor series circuit, and regulating a first voltage across the capacitor series circuit,
wherein the control circuit is configured to regulate the first voltage by transferring charge from the first capacitor to the second capacitor,
wherein the control circuit is further configured to monitor an input voltage received by the power source and operate the buffer circuit in the second operating mode when the input voltage is zero for longer than a predefined time period.
