From the project

Two-board wireless charging system modeled on an electric toothbrush; custom PCBs designed in KiCad with inductive coupling for power transfer.

A two-board wireless power transfer system modelled on an electric toothbrush charger, designed as part of a group university project.

The system consists of two custom PCBs communicating through inductive coupling: a primary board acting as the charger base, and a secondary board acting as the battery pack receiver. Component values were calculated individually for the specific power transfer requirements rather than taken directly from a reference design.
