If graphite plasma wastewater cannot be properly treated, it may cause serious pollution to the natural environment. In this paper, the conditions of wastewater degradation by high-voltage pulse discharge are optimized. On this basis, it is proposed to improve the discharge power supply and reactor to effectively strengthen the discharge and improve the degradation rate of organic matter. The wastewater is degraded by high-voltage pulse discharge and coagulation Fenton oxidation. The specific degradation effect is as follows: when the initial pH of aeration is about 10.00 mm and the initial pH of aeration is about 80 mm/L, the specific degradation effect of wastewater is about 1.00-200 mm. The degradation rate of chemical oxygen demand in 120 min can reach 49.84%. The graphite plasma wastewater treatment system designed based on the Internet of things platform has made a great contribution to the balance between industrial production and natural environment in China.

“…A unipolar excitation voltage can be generated with the power supplies based on the flyback or forward circuit. 24,25 Although this type of power supply has a compact structure, it is easy to cause a voltage oscillation on DBD loads, magnetic saturation of transformer and transformer heating fault. A bipolar pulsed excitation voltage on DBD loads can be generated with a power supply based on Marx circuits [26][27][28] or multilevel circuits.…”

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.

“…The first type is called the wave-continuous resonant voltage excitation, and the series-load resonant and parallel-load voltage excitation are representatives (Chang et al , 2014; Lopez-Fernandez et al , 2015). The second type can be named the wave-discontinuous resonant voltage excitation, and the voltage excitation based on the flyback circuit is the representative (Dhakar et al , 2021; Yamashita et al , 2015; Ram et al , 2018; Achour et al , 2017). The power supply based on the multistage voltage superposition principle is the third type of power supply, whose representatives are the Marx-type power supply (Wang et al , 2018; Rao and Kolb, 2017; Liu et al , 2019) and the multilevel type power supply (Dragonas et al , 2015; Saleh et al , 2018).…”

“…Although the second type of power supply has a compact structure, it is easy to cause a voltage oscillation on DBD loads (Davari et al , 2013), which makes it difficult to generate a high-quality voltage excitation. To solve this problem, a feedback diode (Rai et al , 2018) and a parallel absorption circuit on the secondary side of the transformer (Dhakar et al , 2021) are introduced in the flyback converter. However, with the introduction of the feedback diode, a high voltage would be applied to this diode.…”

Purpose How to use a simple and classical topology to provide a high-efficiency excitation voltage for dielectric barrier discharge (DBD) loads is one of the primary problems to be solved for DBD application fields. Design/methodology/approach To address the issue, a set of modes that can generate a high-efficiency pulse excitation voltage in a full-bridge inverter are adopted. With the set of modes, the unique equivalent circuit of DBD loads and the parasitic parameter of the step-up transformer can be fully used. Based on the set of modes, a control strategy for the full-bridge inverter is designed. To test the performance of the power supply, a simulation model is established and an experimental prototype is made with a DBD excimer lamp. Findings The simulation and experimental results show that not only a high-efficiency excitation voltage can be generated for the DBD load, but also the soft switching of all power switch is realized. Besides this, with the set of modes and the proposed control strategy, the inverter can operate in a high frequency. Compared with other types of power supplies, the power supply used in the paper can fully take advantage of the potential of the excimer lamp at the same input power. Originality/value This work considers that how to use a simple and classical topology to provide a high-efficiency excitation voltage for DBD loads is one of the primary problems to be solved for DBD application fields.
