摘要

脉冲电源,如快速电容器组和磁通压缩发电机可以提供几十兆安培的电流,但需要从几到几十微秒才能达到输出水平。为达到每微秒几十厘米的速度而设计的等离子体负载需要这种量级的电流脉冲,但在几百纳秒内就能发挥作用。使用前者驱动后者需要一个转换开关,该转换开关可以在较长的时间尺度上以低损耗传导这些电流,并在较短的时间尺度上将电流切换到负载。

Three-dimensional MHD simulations of a plasma opening switch
Pulsed power sources such as fast capacitor banks and flux compression generators can deliver tens of mega-amperes of current but require from a few to few tens of microseconds to reach that level of output. Plasma loads designed to achieve velocities of tens of centimeters per microseconds need current pulses of that magnitude but function in a few hundred nanoseconds. Using the former to drive the latter requires a transfer switch that can conduct those currents for the longer time scale with low losses and switch the current to the load in the shorter time scale.
