Abstract
Power supply units (PSU) provide for digital current-sharing loop control to ensure output voltage regulation during dynamic load transients by (i) delaying an internal current signal to match a delay in a shared current signal, and (ii) controlling the output amplifier based on the shared current signal and the delayed local current signal to maintain the respective local DC electrical power in proportion to contributions by other ones of the more than one PSU to the shared DC electrical power and thereby avoid instability in dynamic response to a load transient induced by the power consuming component.
