Design and Analysis of Class EF2 Inverter for Driving Transmitting Printed Spiral Coil
Mohammad Haerinia Ebrahim S. Afjei
This paper studies a high frequency inverter for low power applications at short distance. Class EF2 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.
