Abstract: High-voltage square-wave nanosecond pulse generator has a broad application prospect in the fields of atmosphericn low-temperature plasma, biomedicine and power equipment detection. Pulse forming line is an effective way to realize high-voltage square-wave nanosecond pulse output.
It is mentioned in refs. [18–20] that the inductor is used as the secondary energy storage element to discharge pulses on the load through the cooperative action of the switch. The pulse amplitude obtained on the load will be higher than that on the primary energy storage unit so as to get a higher voltage gain.
The DC charging po-wer supply is KA6003D (KORAD, 60 V). The load uses thick film non‐inductive resistors with a very low stray inductance. All transmission lines used are double‐layer shielded lines, with the aim of reducing spatial interference between lines. Nano-crystalline materials with high initial permeability are used as the core of VITLT.
Pulse on the primary side with amplitude of 1 kV, pulse width and rise time of 10 and 3.2 ns are generated using the pulse forming part. Voltage on the secondary side of the VITLT becomes 2 kV. The pulse width and rise time are 10.8 and 3.5 ns, respectively. From the amplitude of the pulse voltage, VITLT can achieve a double voltage boost.
Comparing both the pulse rise time and width, there is not much differ-ence, which means that the loss of a high‐frequency compo-nent of the pulse is very small after the VITLT boost. The single‐module experiment verifies the topology prin-ciple and the boost effect of VITLT on a short nanosecond pulse.
