摘要：The present invention discloses a high efficiency charging system and a chargingcircuit therein. The high efficiency charging system includes a power supplier and a powerreceiver, which are connected via a transmission wire so that power is transmitted from

the power supplier to the power receiver. The power receiver includes a voltageconversion circuit and a control circuit. The voltage conversion circuit converts anadjustable input voltage provided by the power supplier to an output voltage andgenerates an output current for charging a battery. The voltage conversion circuitadaptively adjusts the output current according to a voltage drop between the

adjustable input voltage and the output voltage. The control circuit senses the adjustableinput voltage and the output voltage and instructs the power supplier to adjust theoutput voltage according to the voltage drop between the adjustable input voltage andoutput voltage.
