Optimal Design of the Charging System for Transcranial Magnetic Stimulation

The charging technology of the energy storage capacitor is the key to the implementation of the stimulated coil charging power supply. In this paper, based on the background of current power demand for stimulation coils used in transcranial magnetic stimulation, a small stimulation coil power supply device is developed based on series resonant capacitor charging technique with the stimulation coil as the target load. After the preliminary study of resonant constant-current charging theory, the component parameters were designed and the physical platform was built with simulation-aided tools, and the experimental debugging was carried out to finally achieve the expected charging target for basic transcranial magnetic stimulation.
