Abstract

Inductive power links are a popular method of wirelessly transferring power to small devices. High efficiency power transmitters such as the Class-E transmitter are the preferred choice for frequencies up to the low MHz range, however at frequencies above 100 MHz, the circuit does not produce a high enough efficiency. This paper investigates the consideration of parasitic elements of the transmission coils in the circuits, showing an improvement in the circuit's performance.
