摘要
为了探索一种更加紧凑的导轨型电磁推进基础实验用脉冲电源,以实验室现有高温超导储能脉冲变压器为单元模型,在单谐振电路脉冲成形方案的基础上,设计了环形结构的多模块脉冲电源,分析了环形结构中考虑互感的多模脉冲电源电路的充放电过程。通过对八模块环形结构脉冲电源进行仿真分析,得到了接近150kA的电流脉冲,原边电压限制13kV左右。可以得出,利用单谐振电路的多模块超导储能脉冲变压器并联放电方式,可以实现大电流脉冲的输出的要求,而且环形结构中各线圈存在的互感更有利于多模块脉冲电源。
In order to explore a more compact rail - type electromagnetic propulsion pulsed power supply for basic experi- ment, on the basis of the single resonant circuit pulse forming scheme, a multi - module pulse power supply of the toroidal struc- ture was designed by using the existing high - temperature superconducting pulsed power transformer as a unit model. This paper analyzed the charge and discharge process of multi - module pulsed power supply circuit in the toroidal structure which considered the mutual inductance. By simulating and analyzing the eight modules pulsed power supply of the toroidal structure, a current pulse close to 150kA was obtained and the primary voltage was limited to about 13kV. This paper concluded that a large current pulse can be achieved by using multi - module superconducting pulsed power transformers to discharge in parallel with the single resonant circuit module, and mutual inductance of each coil in the toroidal structure is more conducive to multi - module pulsed power supply.
