线性变压器驱动器可以在数百纳秒内产生兆安电流，从而可以在极端条件下产生物质并在实验室环境中对其进行研究。使用该技术的驱动器比 Marx-banks 驱动器更紧凑，但具有非常相似的特征。关键组件是磁芯，它允许在直流阶段（当磁芯电感是电路的可忽略部分时）对系统进行并联充电；以及在脉冲阶段（当磁芯提供电感隔离时）对系统进行串联放电。然而，磁芯增加了系统的重量、成本和设备的占地面积。在本文中，我们展示了如何用绝缘体断裂来代替磁芯，从而提供电容隔离。与具有核心或无隔离的系统相比，这种方法减少了系统的重量和占地面积，同时最大限度地减少了电流损耗。
Linear transformer drivers can generate mega-amperes in hundreds of nanoseconds, allowing to produce matter under extreme conditions and study it in a laboratory setting. Drivers using this technology are more compact than Marx-banks drivers but have very similar characteristics. The key component is the magnetic core that allows to charge the system in parallel, during the dc phase when the core inductance is an ignorable part of the circuit, and to discharge it in series, during the pulsed phase when the core provides inductive isolation. However, the magnetic core increases the weight, the cost of the system, and the footprint of the device. In this article, we show how the magnetic core can be replaced by an insulator break, providing capacitive isolation instead. This approach reduces both weight and footprint of the system while minimizing current losses compared with a system with cores or no isolation whatsoever.
