“…In [21], a historical account of the development of Marx circuit and synchronous isolated driving techniques for switches is provided, it solely focuses on Marx type generators. In [9], a review of research on solid-state generators based on inductive energy storage and semiconductor opening switches (SOS) is presented, while in [22], pulse generators for water treatment applications are reviewed. However, there is still a lack of a comprehensive overview encompassing the various power electronics intensive HVPG topologies for various applications.…”

With the advancements in power semiconductors and converters, power electronics based high-voltage pulse generators (HVPG) have emerged due to their advantages of high repetition rate, flexible control, long lifetime, and compact size. However, there is a lack of comprehensive literature review on recent advances in power electronics intensive HVPG technologies. To fill this gap, we present a systematic review on HVPGs. First, HVPGs are classified into different types based on their mechanisms. Each type along with its basic circuits and modifications are introduced. Then, the characteristics, advantages, and disadvantages of these topologies are summarized. Furthermore, the potential applications of HVPGs are explored. The performance of pulse generators mentioned in the literature and commercial products is listed. Finally, future trends and technical challenges in HVPG design and development are discussed. This paper provides a clear understanding of HVPGs and the inspiration of topologies developments to meet the specific requirements. Current state and potential future directions are discussed and summarized to facilitate evolvements in HVPG technology.INDEX TERMS Pulsed power supply, high voltage, pulse generator, power electronics.

“…However, many traditional methods create unwanted products in addition to water purification, or there are restrictions on their use. One of the new methods for using in water purification is the pulse power system method, which uses high voltage pulses to purify water in a short time (Akiyama et al , 2007; Guo et al , 2020; Sugai et al , 2010; Suzuki et al , 2011). The pulsed high voltage application in this system can cause some reactions in the treated material.…”

Purpose To design a pulse power water treatment system, it is necessary to design a reactor optimally. One of the most essential types of reactors used in water treatment is the dielectric barrier discharge (DBD) reactor. The purpose of this paper is to model the electric field in the two types of planar and coaxial reactors to have an accurate analytical formula for using in the optimal design according to the required electric field of the treatment. Design/methodology/approach The method proposed in this paper focuses on the voltage of different areas in the reactor and different boundary conditions to obtain the surface charge density. In this regard, parameters of the dielectric and treated material, as well as the reactor dimension, have been affected in the equations. To confirm the analytical results, the finite element method simulation has been performed, and it shows the accuracy of this method. Findings The exact analytical equation of the electric field is found within the discharge zone of the planar and coaxial DBD reactors. These equations can predict the values of different parameters of the reactor required to purify the material before each design and it does not even require simulation. Originality/value The electric field formula presented in this paper can allow the manufacturers of pulse power water treatment systems to optimize their design easily, cost-effectively and in less time. Also, the formulas provided are completely general and remain effective for all materials.

Under air flotation conditions, the effect of an electric field (EF) to the interfacial properties of hydrophobic particles in salt solution was investigated by using molecular dynamics simulation. The varieties of thickness of the hydrophobic layer on the surface of the hydrophobic particles, radial distribution function of Na + , diffusivity of CO 2 and H 2 O, residence time of H 2 O in the solvent shell of Na + , and the distribution of CO 2 near the graphene caused by the applied EF in different NaCl systems were calculated, and all those results were compared with those where there is no EF applied. The results reveal that the thickness of the hydrophobic layer near the hydrophobic particles is decreased under an EF. The coordination number and residence time of H 2 O in the solvent shell of Na + are also decreased, which indicates that the restraint of Na + on surrounding H 2 O is weakened, and the H 2 O molecules are more mobile. Under an external EF, the diffusion coefficient of CO 2 and H 2 O is increased, and the quantity of CO 2 near the surface of graphene is decreased according to the numerical results of the radial distribution of graphene−CO 2 . All the results indicate that the EF will decrease the thickness of the hydrophobic layer near hydrophobic particles, which can therefore weaken the adsorption between the hydrophobic particles and the gas molecules. The simulation results in the present study can provide theoretical support for brine mineral flotation under an external EF.
