Power supply control system, load apparatus and method

Abstract

A system, load apparatus and method for power supply control are provided. In a power supply control system, a power supply apparatus supplies an initial voltage, a load apparatus receives the initial voltage from a first node and transmits, via a second node, a feedback current signal having at least a first information feature generated by a first circuit module and a second information feature generated by a second circuit module. The power supply apparatus detects the first information feature to determine a first power supply parameter, detects the second information feature to determine a second power supply parameter, and supplies electric power based on the first power supply parameter and the second power supply parameter, wherein the first power supply parameter is one of voltage, current or wattage, and the second power supply parameter is another of voltage, current or wattage.
