The effect of self-inductance on the power characteristics of inductive systems for power transfer to implants based on coupled LC circuits with series compensation was studied. Nine coil pairs for systems with operating frequencies of 220, 440 and 880 kHz were studied. Of these, three coil pairs were from systems based on the mutual inductance control technique; six pairs, from systems based on the self-inductance control technique. It was shown that a 0.5-1% variation in the self-inductance accompanied by a corresponding change in the geometry of the coils may lead to 15-20% changes in the output power of the system in the nominal position.
