介绍了一种基于级联H桥的经颅磁刺激脉冲发生器。该系统表现出完全的灵活性，在其电气限制范围内产生不同形状，持续时间，方向和刺激脉冲的重复率，并且可以模拟该应用领域迄今为止可用的所有商业和研究系统。与传统的基于载波的脉宽调制相比，用于生成脉冲和序列的离线模型预测控制算法显示出优越的上级性能。一个功能齐全的实验室原型提供高达1.5 kV，6 kA的脉冲，并准备作为一个研究工具，探索经颅磁刺激疗法，利用设计提供的许多自由度。
A cascaded H-bridge based pulse generator for transcranial magnetic stimulation is introduced. The system demonstrates complete flexibility for producing different shape, duration, direction, and rate of repetition of stimulus pulses within its electrical limits, and can emulate all commercial and research systems available to-date in this application space. An offline model predictive control algorithm, used to generate pulses and sequences, shows superior performance compared to conventional carrier-based pulse width modulation. A fully functioning laboratory prototype delivers up to 1.5 kV, 6 kA pulses, and is ready to be used as a research tool for the exploration of transcranial magnetic stimulation therapies by leveraging the many degrees-of-freedom offered by the design.
