摘要
文章对影响感应磁场强度大小的因素进行剖析,在传统经颅磁刺激电路的设计基础上,对于系统安全的提升供电电压、实现长期稳定工作、缓解电路发热等指标进行优化。给储能电容分步充电的创新式设计,提高了磁刺激的频率。经过调试,最终达到在500V高压供电情况下,刺激线圈中产生频率为100Hz的脉冲电流。
In this paper, the factors impacting on the magnetic field intensity are dissected. Such indexes as safely lifting supply voltage level, realizing a long term stable operation, and lessening the heat circuit are optimized on the basis of design of traditional circuit of transcranial magnetic stimulation. The frequency of magnetic stimulation has been improved in the design by charging energy storage capacitor step by step. The pulse current lOOHz can be produced in stimulate coil with 500V after debugging. The rate of change is the right conditions in place where induced magnetic field can be produced.
