Press-pack IGBT: high-current pulse switch transcranial magnetic stimulation

Press-pack IGBTs have exhibited excellent power performance at a range of required pulse current shapes on various industrial applications, including repetitive transcranial magnetic stimulation (rTMS). This presentation describes the design, construction, testing and operation of a 125-mm electrode diameter capsule device used in a high-power pulse switch assembly. The operational assembly test results have shown satisfactory agreement with the design methodology using conventional calculations and simulations.
