摘要：In this paper, the characterization of wireless power charging receiver for mobiledevice developed based on magnetic resonance coupling is presented. The receiver isconstructed of an electromagnetic waves radiator which is implemented by use of microstrippatch on a dielectric substrate to operate at frequency of around 10MHz and a rectifier circuitwhich comprises of a voltage doubler circuit. Prior the hardware realization, the designed ofreceiver is performed through simulation to investigate the influence of level and frequency ofinput voltage to the DC voltage of rectifier circuit output. The radiator efficiency andperformance of rectifier circuit are two things that are focused in the investigation. From theexperimental characterization, it shows that the radiator efficiency for a considerable gap ismore than 37% for some level of varied input AC signal. While the DC voltage of rectifiercircuit output has the voltage deviation less than 2% for operating frequency of input voltagevaried up to 20%. In addition, it is demonstrated that the receiver is able to start charging abattery of mobile phone by producing 4.12VDC at the output of receiver with the gap separationbetween 2 radiators of 0.8mm.
