Abstract:The high frequency series resonance constant current charging technology was used to the power supply system of repeti -tive transcranial magnetic stimulation ( rTMS) which effectively improved the efficiency and reliability of power system of rTMS .The charging voltage error was kept within 5%and the stimulated frequency increased from the original a few Hz to more than 10 Hz.We designed the digital control system choosing STM 32 chip as the core , which improved the controllability of system , solved the problems of unable to program and poor controllability caused by traditional analog control modem .Finally, we built experimental prototype con-necting the transcranial magnetic stimulator , the stimulated frequency reached up to 31 Hz at 500 V and reached up to 20 Hz at 1000 V.
