Abstract
A current measurement control system for a power supply system is provided. The current measurement control system includes a load module that estimates a total load of the power supply system. An amplification module selectively determines an amplification factor based on the total load and amplifies a current signal based on the amplification factor. A current measurement module measures current based on the amplified current signal.
