Abstract
An adaptive power supply system is designed to adaptively supply an electrical power from a plurality of input voltages to an electronic device in accordance with the load of the electronic device. The power supply system includes first and second groups of voltage conversion circuit loops, having input terminals respectively connected to a first input and second input voltages. Each voltage conversion circuit loop includes a switching circuit to which an associated control signal from a controller is coupled for controlling on/off states of the switching circuits. Output terminals of the first and second groups are connected to a common node point to provide a single output voltage to the electronic device.
