“…21 However, this type of excitation voltage is difficult to be achieved by power supplies with a simple structure. For example, a bipolar pulsed excitation voltage on DBD loads can be generated with magnetic compression type power supplies, 22,23 but the number of magnetic compression circuits increases in proportion to the voltage level of the excitation voltage for DBD loads. With the increase in the number of magnetic compression circuits, the working frequency of this type of power supply is decreased and the design of the magnetic compression circuits becomes more difficult.…”

SummaryAn excitation voltage with a high rising rate, falling rate, and idle time simultaneously is beneficial to taking advantage of the potential of dielectric barrier discharge (DBD) loads. However, how to generate this kind of excitation voltage with a simple structure is rarely researched. To address the issue, a novel LC‐based bipolar high‐voltage pulsed power supply is proposed in this paper. The proposed power supply is comprised of an inductance, two capacitances, a step‐up transformer, and two power switches sharing the same ground. By planning the switch sequence of the two power switches, a resonant stage and an idle stage are formed. The resonant stage is used to generate a bipolar pulse excitation voltage on DBD excimer lamps and an idle time in the excitation voltage is generated in the idle stage. The characteristics and the parameters design of the proposed power supply are studied by theoretical analysis. To verify the feasibility of the proposed power supply, an experimental setup is built with a DBD‐type excimer lamp. The experimental results show that the power supply not only better takes advantage of the potential of DBD excimer lamps, but also there is a fine luminous regulation feature for the excimer lamp. Besides these characteristics, the proposed power supply has several other benefits, such as good adaptability to different DBD‐type excimer lamps, a small number of components, and high efficiency.

“…Atmospheric-pressure nonthermal plasma (APNTP) has attracted much attention in numerous applications, such as material processing [1], pollutant degradation [2], and biological sterilization [3], because it does not use vacuum and the cost of generating it is low [4,5].

Numerous studies have been conducted on pulse dielectric barrier discharge (DBD) because it can produce powerful discharges uniformly at atmospheric pressure with a fast rise time. Although much research has been conducted on pulse DBD below 10 kHz, relatively little has been conducted on pulse DBD at high pulse repetition rates (PRRs). Therefore, in this study, the ozone generation and discharge characteristics of bipolar pulse DBD in atmospheric-pressure air at a high PRR of 10 kHz or above were investigated. According to the results of this study, with the exception of electron temperature, most discharge characteristics need for practical applications—like transfer charge, electron density, and discharge uniformity—improved as the voltage and duty ratio increased at high PRR. On the contrary, increasing the PRR exhibited trade-off features like low electron temperature, low discharge uniformity, and a high number of discharges per unit time. Ozone generation demonstrated good results at high voltage, appropriate PRR, and low duty ratio, but applying suitable electrical conditions is crucial considering ozone generation speed and power consumption. The findings of this study will be very beneficial for high-PRR pulse DBD applications that require quick and effective processing. Additionally, they will be useful for researching the characteristics of pulse DBD at high PRR.

“…For this reason, many studies were carried out to develop robust, efficient, flexible, and easy-to-use generators. Many of them are based on the classical architecture of a Marx generator (shown in Figure 1), such as in [13][14][15][16][17], transmission lines and Blumleinbased generators [18,19], RLC pulse-forming networks [20], and pulse transformer-based generators [21]. Besides biomedical treatments, pulsed power technologies have many other applications, such as plasma science [22][23][24], industrial process [25], ultrawideband radiation, and EMP generation [26][27][28][29].…”

The application of the nanosecond pulsed electric field (nsPEF) for biomedical treatments has gained more interest in recent decades due to the development of pulsed power technologies which provides the ability to control the electric field dose applied during tests. In this context, the proposed paper describes a new architecture of solid-state high-voltage pulse generators (SS-HVPG) designed to generate fully customised sequences of quasi-rectangular pulses. The idea is based on the combination of semiconductor switches (IGBT/MOSFET) known for their flexibility and controllability with special magnetic switches to build compact and modular generators. The proposed structure is inspired by the most known pulse generator of Marx, but mixes its two variants for negative and positive polarities. Thus, the polarity of the generated pulses can be freely selected. In addition to that, the use of IGBTs/MOSFET ensures a tunable repetition rate and pulse width. The capacitors are charged via a series of magnetic switches and a flyback DC–DC converter which provides fast and efficient charging and also an adjustable amplitude of the output pulses. The design can be easily simplified giving two other modified structures, based on the same idea, for mono-polar operating (only positive or only negative pulses) with a reduced number of switches. A SPICE simulation of the generator and results of experimental tests carried out on a three stages generator are presented. The obtained results confirm the operating principle and the claimed performances of the new structure.
