Solid-State Marx Generator Circuit Based on Inductive Energy Storage

Solid-state Marx generator circuits have been widely studied in recent years. Most of them are based on capacitive energy storage (CES), with the basic principle of charging in parallel and discharging in series. In this article, we propose a solid-state Marx circuit using inductive energy storage, where inductors play the role of principal energy storage element. When combined with an opening switch, the inductor can generate an output voltage of L dI/dt, where I is the inductor current. Multiple circuits can be stacked to obtain output voltage adding, as in Marx circuit using CES. In the demonstration experiments, the test on a four-stage inductive Marx circuit has been carried out. With the charging voltage of -200 V, the output peak voltage of ~9.2 kV was generated on an 800-Ω load with a rise time of ~46 ns.
