Abstract
A power interface system for reducing power variations includes multiple control circuits configured to control a plurality of switching regulators operating at different frequencies to provide a shared output power to a load. Each control circuit receives a power variation signal resulting from a power variation in the shared output power of the plurality of switching regulators, separates a respective frequency component from multiple frequency components of the power variation signal, and controls, based on the separated respective frequency component, a respective switching regulator of the plurality of switching regulators to source current to, or sink current from, the shared output power until the shared output power reaches a threshold level.
