Abstract: Design of the radio-frequency power links to be used in prosthetic body implanted systems is important. In this study, we present a novel design procedure for the coil design considering both the efficiency of the system and the radiated magnetic field. Closed loop class-E driver design for low-Q networks is also presented along with the coil design. Main specifications used in the design procedure are dimensions of the coils, distance between them, frequency of operation, load power, load voltage and the maximum available input DC voltage. Experimental results showed an overall power link efficiency of 65% delivering 250mW power to a 16V DC load from an optimal distance of 7mm.
