초록

기존의 경두개 자극장치는 일정한 자극치료 펄스의 정현파 모양으로 다양한 치료 및 진단을 하는데 한계가 있다. 본 연구에서, 치료 및 진단마다 요구되는 세기, 폭, 펄스모양이 다른 코로로프트-월톤회로와 반파브리지 공진 인버터를 도입하여 주파수와 전압이 가변되는 새로운 장치를 제안하고자 한다. 기존장치 보다 많은 장점을 가진다. 첫째로 고압 변압기를 가지지 않는다. 둘째로 스위칭손실이 적고, 출력에너지를 정밀하게 제어할 수가 있다. 세째로 자극의 세기, 폭, 펄스모양이 다양하다. 결과적으로 변압기를 사용하지 않는 반파브리지 인버터와 코크로프트-월톤회로를 적용하여 개선된 특성과 실험을 구하였다.

Though existent a transcranial magnetic stimulation makes various treatment and diagnostic sine waveform of fixed stimulation pulse, there is limitation. In this research, because strength, pulse width, pulse pattern required in treatment and diagnostic introduce other Cockroft-Walton circuit and half bridge inverter frequency and voltage variable become new device propose wish to. Have more advantages than existing device. First, do not have high voltage transformer. Second, switching loss can be less, and control output energy precisely. Three, stimulation strengths, pulse width, pulse pattern are various. As a result, sought special quality and an experiment that is improved applying inverter and cockroft - Walton circuit is half bridge inverter that do not use transformer.
