Summary This thesis work aims to realize a wireless power transfer class-E DC-DC converter controlled by an innovative method. The circuit is composed of a primary and a secondary side which are isolated and works like an inverter and a rectifier stage coupled by two inductor coils (i.e. two coupled coils that work as a transformer with low coupling factor k). The wireless class-E converter is usually designed for a specific load value and a specific k and only in this configuration the optimal solution is guaranteed. Furthermore, this circuit is very sensitive to variations in the load (the simplification of the time-variant electronics that must be fed by the converter) or the coupling factor (changing with distance, misalignment or medium between the coils).
