A wireless energy transfer system was developed using multiple transmitting coils and a full bridge inverter at 85 kHz. The system consisted of three identical transmitter coils and one receiver coil. The study aimed to assess the impact of a tuned capacity array on the system's efficiency for various receiver coil placements. The experiment was conducted in eight different placements, with and without capacity tuning. The simulation showed that the efficiency ranged from 87.5% to 91.5%, while the experimental study showed efficiency between 87.8% and 91.9% under the same conditions. The tuned capacity array was utilized in both studies, resulting in efficiency ranging between 89.3% and 92.8% in the simulation and between 89.5% and 93.1% in the experimental study. The experiment revealed an increase in efficiency of 1.65%, 1.23%, 1.39%, 2.5%, and 1.28% in five different locations (A→E), respectively, while a decrease of 0.4%, 0.89%, and 0.45% was observed in three other locations (F→H), respectively.
