Abstract: An exemplary embodiment of the present invention is a wireless power transmission circuit that that provides power to a load of variable resistance with an alternating current (AC) power source induced at a secondary coil in a secondary side of the circuit by a primary coil in a primary side of the said circuit. The wireless power transmission circuit includes a switch-controlled capacitor (SCC) and a semi-active rectifier (SAR). The SCC connects to the AC power source. The SCC includes a first capacitor connected in parallel with two electrically controllable switches in series. The SAR connects to output of the SCC for rectifying the output of the SCC, wherein the SAR comprises a bridge circuit that includes two electrically controllable switches. Both switches in the SCC are turned on for half a cycle and complement to each other and are turned off with a time delay relative to the zero cross points of the AC power source, and the time delay is a control angle of the SCC. Both switches in the SAR are turned on for half a cycle and complement to each other and are turned off with a time delay relative to the zero cross points of the AC power source, and that time delay is a conduction angle of the SAR. The control angle of the SCC and the conduction angle of the SAR are regulated to provide a load impedance that matches the impedance of the coils, so that the wireless power transmission provides constant power output and enhance the power transmission efficiency.
