“…Although the fabrication process was thoroughly explained in [7], here we need to describe the geometry of the spiral stripline since it determines the output pulse shape. The spiral in the present study has 24 turns, which form a bobbin with a total height of 75 mm, outer diameter of 60 mm, and inner diameter of 20 mm.…”

“…Feeding this triggering pulse to the primary winding, common to all 4 ferrite-based transformers, allows to generate simultaneous pulses on the secondary windings, which are connected to the gate electrodes of the SP205-01 thyristors. A detailed description of Sw and DB is provided in [7]. In addition, the DB carries a 5 kV regulated power supply to charge the spiral and an interlock to protect the user.…”

“…Thanks to the advantages of modern semiconductor technology, an all-solid-state spiral generator [7] has been tested in this work as a prototype of the SOS diode pumping circuit. A spark gap, traditionally used in the spiral generator, was replaced by highly interdigitated thyristors [8] that are commercially available under the Solidtron brand [9].…”

The trigger generator made with a spiral generator (SG) has the advantages of light weight, compact structure, and low cost and has promising applications in the pulsed power field. This paper introduces a compact solid-state high-voltage pulse trigger system based on an improved SG, which has improved repetition rate and lowered the demands for semiconductor switches’ maximum current and current rise rate when compared with previous studies. The improvement is achieved by winding outward an additional layer of the passive layer and low-voltage metal strip, which realizes a significant reduction of the peak current and current rise rate of the discharge switch. The final dimension of the trigger is 25 × 10 × 10 cm3, excluding the power supply. An experiment carried out in single shot mode shows that the peak value of the output pulse can reach 50 kV with a leading edge of 57 ns. Repetitive experiments were carried out up to 1 kHz, with the peak voltage of the output pulse being 30.5 kV, the leading edge being 48 ns, and the jitter being 0.84 ns. Finally, the generator is used to trigger a gas switch, and it works stably and reliably.

Rolled strip pulse forming line (RSPFL) with combined insulation structure can effectively increase the breakdown electric strength and energy storage density of pulse forming line by optimization of the edge field enhancement effect. In this paper, a combined insulation (which consists of polyimide and polyvinylidene fluoride films) based RSPFL is investigated theoretically and numerically. Firstly, parameters of the pulse forming line was designed theoretically. Secondly, the finite element software was employed to study the influence of insulation film combination and structural parameters on the electric field distribution and the transmission characteristics. The parameters are then optimized. Finally, combined insulation based RSPFL was successfully used as a single pulse forming line, and a 200 ns quasi-square pulse was obtained on a 2.5 Ω dummy load by simulation. The simulation shows that it has an energy storage density of approximately 19.57 J/L when the PFL is charged to 60 kV.
