Hill climbing algorithms to enhance the efficiency of inductive power supply systems for implants

Studies have shown that algorithms of the “hill climbing” type can be used in the design of coil pairs in the inductive power supply systems of implants with specified energy transfer stability characteristics (output power drop not greater than a specified value for a specified range of acceptable displacements of the inductors relative to each other). Two algorithms based on the “steepest ascent hill climbing” (SAHC) and “adaptive hill climbing” (AHC) algorithms have been developed to solve the problem of increasing the efficiency of energy transfer while maintaining the specified stability characteristics of energy transfer. The AHC algorithm was shown to allow solutions for a larger set of constants and design variables to be found. At the same time, the SAHC algorithm gave preferable solutions in some cases, so it seems possible to use both algorithms in a design with subsequent selection of a solution depending on the characteristics of the problem.
