Physical design and simulation for a 100 GW LTD system

An eight-switch linear tronsformar driver(LTD) module with 100 kA output capability was designed based on a former four-switch one. The spoke-like eight bricks discharge in parallel to drive the load in the center. A 10-stage 100 GW LTD system was physically designed with the newly designed modules. Circuit simulation with Pspice and particle-in-cell (PIC) simulation were done to assess the system’s physical properties. Simulations have proved that the design is reasonable. Voltage was magnetically and inductively added, and the system can drive a 10 Ω load with 100 GW pulse, with rise time of the pulse less than 60 ns.
