© 2022 IEEE.It is critical to ensure load compatibility of Class-E inverters used in wireless power transmission systems. Two different methods can achieve load matching. The first is provided by adjusting the source voltage, and the second is by adjusting the capacitance in the resonant circuit. The second method is the most frequently used and practical in the literature. In the wireless power transmission system, the distance between the coils changes the inverter load value. The previously designed capacity array simulation study has been implemented in this study. In the application results, the load compatibility of the inverter has been tried to be ensured. As a result of the study, load compatibility of Class-E inverter is provided for variable distances.
