The transcranial magnetic stimulation recharges the energy storing condenser, and sends the stored energy in the condenser to the pulse shaping circuit, which then delivers it to the stimulating coil. The previous types of transcranial magnetic stimulation required a booster transformer, secondary rectifier for high voltages and a condenser for smooth type. The energy storing condenser is recharged by switching the high-voltage direct current power. Loss occurs due to the resistance in the recharging circuit, and the single-pulse output energy in the transcranial magnetic stimulation can be changed because the recharging voltage cannot be adjusted. In this study a booster transformer, which decreases the volume and weight, was not used. Instead, a current resonance inverter was applied to cut down the switching loss. A transcranial magnetic stimulation, which can simultaneously alter the recharging voltage and pulse repeats, was used to examine the output characteristics.

Instead of relying on traditional medical electrotherapy, we seek to determine a more positive approach to early ischemic brain injury by researching the effect of applying a magnetic stimulation device in an SD mouse's brain to stop apoptosis, where a 64-Bit-EISC Processor Core delivers transcranial magnetic stimulation (TMS). We determined the change of the post-ischemic stimulatory effects on the Bax, caspase-3, and immune-reactive perikarya over time by stimulating the mouse's brain. c-Fos and Cox-2 were used to find a crucial determining factor regarding inflammation-related cytotoxicity. The cerebral ischemia caused a biochemical change in the brain tissue and increased the neuronal genes within a few minutes. The genes showed that these very fast reactions involve an early gene. Next, we found an approach that is more favorable than electrotherapy for the apoptosis that is caused by early ischemic brain injury by researching the c-Fos protein that changes largebrain neurons; this was achieved after we stimulated the ischemic mouse brain using a two-tank LLC resonant converter as part of the TMS experimental equipment.
