Abstract:
An apparatus, a method, and a computer program product are provided. The apparatus determines an input voltage and an input current of a power system driving a low power factor load, the input voltage varying based on a power cycle, determines at least a first portion of the power cycle at which the input current exceeds a threshold, and couples at least one substantially resistive load to the low power factor load during at least a second portion of the power cycle different from the at least a first portion of the power cycle.
