Abstract
A predictive power factor control system for an electronic system which includes a power supply providing power at a power supply output to a load having at least one component operable in a plurality of operating states. A load controller selectively determines the operating state of the load. A power factor control (PFC) circuit is coupled to the power supply and cooperates with the power supply to maintain the power factor of the power supply output within desired ranges. The load controller may provide the PFC circuit with a pending load change notification prior to a pending change in the operating state of the controlled load or prior to the activation of additional loads on the power supply output, enabling the PFC circuit to predictively adjust operation to avoid or minimize power factor fluctuations arising from changes in operating state of the load or activation of an additional loads.
