Abstract At first, a class E power amplifier is designed for magnetic coupling resonant wireless power transmission system as the system power. Given that the class E power amplifier performance will be influenced by the load parameters, an optimization of the source coil structure of wireless transmission system is applied to reduce the drop of the system performance caused by class E power amplifier characteristics. Three kinds of the source coil structure are put forward and tested the change of voltage across the load in multiple load cases. The comparative study involves the structures’ influence on the load voltage and the transmission efficiency of the systems under the load coupled condition. The study found that the structure of multiple source coils and single resonance coil can decrease the load voltage variation, caused by the magnetic field distribution, by using the coupling between loads. And under the class E power amplifier, the structure of series of multiple source coils and resonance coils will cause the drop of system performance easily, and the effects on the loads caused by the coupling are very obvious.
