基于脉冲小电流的经颅磁刺激电路设计
资料介绍
为改进传统磁刺激治疗仪需要使用脉冲大电流产生磁场，以及在临界阻尼震荡条件下电路的RLC参数匹配难度大等缺点，根据感应电场产生的原理，提出一种基于低电压，脉冲小电流，用RL电路代替RLC电路的设计。该电路在产生磁场的回路中用＋5V低电压电源代替电容器，通过加快电流的变化速率产生与脉冲大电流同样的刺激效果，具有安全，易调控的优点，也推进了磁刺激治疗仪面向小型、便携、低功耗等方向的发展。
To improve traditional therapy apparatus of magnetic stimulation, which always needs to use large current to generate a magnetic field, and to overcome the shortcomings that it is inconvenient for RLC circuit apparatus to quick - adjusting in critical damping, a design, based on the induce theory of the electric field, is proposed in this pa- per. It uses low voltage and low current, RL circuit instead of RLC circuit and a ＋ 5V low voltage source in place of the capacitor, which is safer, more reliable, more convenient and faster. In turn, it can promote the development of therapy apparatus of magnetic stimulation with smaller and lower power consumption.
