Battery backup based on voltage feed-forward control in a power supply

摘要

The subject innovation relates to providing battery backup for a power supply (e.g., a power supply implemented within a distributed power architecture where multiple power supplies are coupled together) based at least in part on voltage feed-forward control. A backup converter is coupled to a battery and a primary power converter. The backup converter delivers power from the battery to a load when a primary power failure is detected in the primary power converter. A controller controls an output current level of the backup converter based on an output voltage level of the battery.
