Resonant inductive coupling as a potential means for wireless power transfer to printed spiral coil

This paper proposes an inductive coupled wireless power transfer system that analyses the relationship between induced voltage and distance of resonating inductance in a printed circuit spiral coils. The resonant frequency produced by the circuit model of the proposed receiving and transmitting coils are analysed by simulation and laboratory experiment. The outcome of the two results are compared to verify the validity of the proposed inductive coupling system. Experimental measurements are consistent with simulations over a range of frequencies spanning the resonance

Design and Analysis of Class EF\u3csub\u3e2\u3c/sub\u3e Inverter for Driving Transmitting Printed Spiral Coil

This paper studies a high frequency inverter for low power applications at a short distance. Class 2 inverter is selected and designed as a transmitting driver. A printed spiral coil is designed as a transmitting coil and is connected to the high frequency inverter. Experimental results are obtained to compare with simulation results. The experiment and simulation are in good agreement and the circuit design is verified. Operating frequency is 2.75 MHz. Maximum flux density is generated by transmitting coil is measured 149uT
