Abstract In order to improve the energy saving rate of the excitation source, based on cTMS1, a novel energy efficient excitation source topology is proposed and the EEES circuit structure and switch control method are designed in this paper. Firstly, the pulse width is adjusted by controlling the on-time of the switch. Then the circuit topology is designed to realize energy recovery and reuse, which can improve the energy utilization of the system. Finally, the EEES experimental platform is built to verify the system performance. The experimental results demonstrate that the EEES can generate current pulses up to 1 058A with an adjustable pulse range of 5~160μs. Compared with the cTMS1 excitation source, the energy self-loss rate is obviously lower than cTMS1, and the energy saving rate of EEES is as high as 62.60%~93.21%. Therefore, the EEES system proposed in this paper provides an important reference for the development of TMS excitation source.
