Resonant Inductive Coupling Wireless Power Transfer of Multiple Devices

The study uses inductive resonance coupling to analyze a wireless power transfer system's frequency resonance, voltage, goal load power, and current rating to calculate the number of output devices the system can activate simultaneously. The researchers ran trials via each output device to test the voltage, current output, and load power rating on as many as three devices simultaneously. Testing can be done to get the measured output load values at specific heights between the transmitter coil and the receiver pads by calibrating the best horizontal placements of the receiver pads on the transmitter coil. The resonant frequency was calculated so that electromagnetic induction would occur between the transmitter and receiver circuits. The trials' data show that the output device's voltage, current, and power needs affect the maximum elevation between the transmitter and receiver components. The results show that as the height between the transmitter and reception coil rises, the power rating of the load decreases. To sum up, elevation impacts the maximum power that a specific output load can generate.
