摘要： The present invention provides a wireless power transmission system having capability to supply mobile side DC load voltages at a plurality of voltage levels at minimized system manufacturing costs. An adaptive mobile side rectifier circuit operates in a full bridge rectifying mode or a half bridge rectifying mode depending on the voltage level of a mobile side load voltage to be supplied. A rectifying mode controller switches to the full bridge rectifying mode during supply of the mobile side load voltage at a lower load voltage level and switches to the half bridge rectifying mode during supply of the mobile load voltage at a higher load voltage level. The present invention also relates to a method of controlling the adaptive mobile side rectifier circuit.
