  • Publication number: 20240283352
    Abstract: Controlling power factor correction (PFC) in a flyback converter is described. In one embodiment, an apparatus includes a flyback converter configured to operate with a variable switching frequency. The flyback converter includes a signal transformer, a primary side including a primary-side controller coupled to the signal transformer, and a secondary side including a secondary-side controller coupled to the signal transformer. The secondary-side controller is configured at least to cause a control signal to be generated based on a set of parameters. The control signal controls power factor correction (PFC) for the flyback converter.

  • Publication number: 20240283363
    Abstract: Controlling power factor correction (PFC) in a flyback converter is described. In one embodiment, an apparatus includes a flyback converter configured to operate with a fixed switching frequency. The flyback converter includes a signal transformer, a primary side including a primary-side controller coupled to the signal transformer, and a secondary side including a secondary-side controller coupled to the signal transformer. The secondary-side controller is configured at least to cause a control signal to be generated based on a ramp voltage generated by a ramp voltage generator of the secondary-side controller. The control signal provides power factor correction (PFC) using the flyback converter.

  • Patent number: 10372557
    Abstract: In one example, a method may include generating, by a computing device, a volume as a file in memory, where the volume may be based on an operating system (OS) image. The method may include attaching the file to a workload, booting the workload using the OS image, generating a version of the file with at least one block that underwent change and metadata associated with the change based on an input/output request to the volume, storing, by the computing device, the file and the version of the file on a storage device associated with the computing device, and recovering a version of the volume associated with the workload using the file and the version of the file stored in the storage device.
