“…A quasirectangular pulse waveform can be achieved by using PFN, and PFNs consisting of identical inductors and capacitors connected in cascades by ladder style are generally used [9,10]. As for Blumlein PFN, it has the advantage that the peak output pulse voltage is equal to the charging voltage, which reduces the system insulation requirements.…”

With the development of high-power microwave technology, the output power of the pulse generator is required more and more higher. In this paper, it is realized by increasing the output power of the module while the output impedance of the module changes little. The module of the generator is based on pulse forming network (PFN) and linear transformer (LT). Four Blumlein PFNs with arc-type configuration and 24 Ω characteristic impedance were connected symmetrically to the primary coil of the LTD and driven by two identical laser triggered spark switches to ensure four Blumlein PFNs synchronizing operation. On this basis, a two-stage high-power pulse generator based on PFN-LT is developed. The following technical parameters of the generator were achieved on a 12 Ω high-power solid resistor: output voltage amplitude of ∼250 kV and output power of ∼5.2 GW at a repetition rate of 5 Hz.

“…Fig. 3(a) shows a bipolar pulse forming network, which adopts an LC ladder architecture to produce rectangular impulses [10]. However, this topology is not flexible to operate and requires a high-voltage input source itself because it is not able to step-up the input voltage.…”

“…Among these, one alternative is to have a cascade arrangement of inductors and capacitors [5], [10], however, this design requires a high-voltage source and is not flexible enough for the intended broad sets of applications discussed here. Some other previous works generate highvoltage spikes by attempting to interrupt a flux in a magnetic core [11], [12], but these circuits have a complicated magnetic design, usually create significant stress on the switches, and generally, do not produce square pulses.…”

This paper presents a high-voltage bipolar rectangular pulse generator using a solid-state boosting front-end and an H-bridge output stage. The topology generates rectangular pulses with fast enough rise time and allows easy step-up input voltage. In addition, the circuit is able to adjust positive or negative pulsewidth, dead time between two pulses, and operating frequency. The topology can also be controlled to produce unipolar pulses and other pulse patterns without changing its configuration. With an appropriate dc source, the output voltage can also be adjusted to requirements of different applications. The intended application for such a circuit is algal cell membrane rupture for oil extraction, although additional applications, include biotechnology and plasma sciences, medicine, and food industry. A 1 kV/200 A bipolar solid-state pulse generator was fabricated to validate the theoretical analysis presented in this paper. In addition, to validate the analysis with simulations and prototype tests, biological test were conducted in order to examine the technical value of the proposed circuit. These evaluations seem to suggest that oil production rate from bipolar pulses may double that of an equivalent process with unipolar pulses.

“…Marx generator is a circuit with multi-stage voltage multiplier [1,2]. Since the Marx generator has many applications in various fields, it has been attracting many researcher`s attention, for example development of 6-stage Marx generator with 100 kA output and 12-stage Marx generator with 5 kJ output [3,4], switch-capacitor cells used for solid-state Marx generator to produce -4 to 4-kV amplitude is presented in [5], pulse-forming network based Marx generator was reported in [6], and output voltage characteristics based on spark gap breakdown voltage was evaluated in [7]. On the other hand, the Marx generator is also useful for charging storage capacitor (SC) of voltage-current impulse generator.…”

In this paper, a Marx generator voltage multiplier as an impulse generator made of multi-stage resistors and capacitors to generate a high voltage is proposed. In order to generate a high voltage pulse, a number of capacitors are connected in parallel to charge up during on time and then in series to generate higher voltage during off period. In this research, a 6kV Marx generator voltage multiplier is designed using gas discharge tube (GDT) as an electronic switch to breakdown voltage. The Marx generator circuit is designed to charge the storage capacitor for high impulse voltage and current generator applications. According to IEC 61000-4-5 class 4 standards, the storage capacitor must be charged up to 4 kV. The results show that the proposed Marx generator can produce voltages up to 6.8 kV. However, the storage capacitor could be charged up to 1 kV, instead of 4 kV in the standard. That is because the output impulse voltage has narrow time period.
