“…This is an important fact considering that the load is the ozone generator. As reported in Ponce et al and Kinnares and Hothongkham a higher frequency applied to the DBD increases the parasitic currents in the electrodes of the DBD heating the electrodes and, consequently, increasing the temperature in the ozone chamber. On the other hand, a higher frequency of the signal applied to the DBD generates more intense discharges, increasing the ozone production.…”

Summary In this paper, the analysis, design, and implementation of a power supply based on a multi‐stage‐shunt class E amplifier applied to ozone generation are presented. The proposed topology operates with pulsating waveforms and allows unidirectional energy flow from the power supply to the load with no energy return. Furthermore, due to the multi‐stage operation, it presents a lower stress in the switches compared with other similar topologies. To validate the proposed topology, a prototype was designed to feed a set of ozone generating cells in a power range of 0 to 500 W. This prototype provides an efficiency of 95% with an ozone production of 10.5 g/h and efficacy of 22.89 g/kWh. The proposed power supply is an alternative to feed any other type of dielectric barrier discharge load while keeping the efficiency of the power supply above 90%.

“…When high-frequency electric fields are applied to the steel plates, parasitic currents are induced in them due to Faraday Law. 25,26 If the frequency is high enough, the generated heat by the plates will destroy the ozone. For this reason, the ozone generators rarely work at frequencies higher than 20 to 30 kHz.…”

“…Because this kind of equivalent circuit model is built under the specified conditions, the expressions describing the characteristics of OGs are used only under the conditions. By substituting the capacitor C g with a sinusoidal voltage under nominal conditions, a linear model and a non-linear model are presented respectively in [14]. Unfortunately, the model is used in nominal conditions rather than a wide working range.…”

Dielectric Barrier Discharge (DBD) type ozone generators (OGs) are widely used for industrial ozone generation. As OGs are typical non-linear load, different models are presented to analyze the characteristic of OGs and the models of OGs have proven to be an effective tool to design power supplies for OGs. However, most of the models are only applicable to nominal conditions and not suitable for a wide working range at present. Considering that almost all of the series resonant inverters use resonant tanks operating in resonance or near of it, the current through OGs can be substituted by a sinusoidal current source with variable amplitude and frequency. According to the concept, a wide-range frequency model composed of an equivalent resistance in series of an equivalent capacitance for OGs is proposed. Because the equivalent resistance and the equivalent capacitance are closely related to switching frequency of inverter and the current through OGs, the model can be used in the wide working range. Based on the model, the characteristic of OGs is analyzed and a methodology for power supplies is developed. Through a combination of the proposed model and the four limit parameters of ozone generators and power supplies in the methodology, the main circuit parameters of the power supply for maximizing the ability of OGs are obtained. To validate the wide-range frequency model and the design methodology, an ozone generation system powered by a 14-kW series resonant inverter is built. The differences between the experimental results and the analytical results show that the proposed model has satisfying accuracy in a wide working range. Compare to the conventional methodology for power supplies, the main circuit parameters of the power supply can be obtained conveniently regardless of the heavy-load condition and light-load condition of OGs.

Plasma is widely used in sterilization and disinfection, environmental treatment, and material surface modification. At present, the DBD load equivalent circuit model used in the design of dielectric barrier discharge (DBD) low-temperature plasma generator power supply mainly includes the nonlinear clamping model and linear resistance capacitance model, which have advantages and disadvantages in the research and application of DBD load. This paper focuses on the modeling and parameter acquisition method of the RC parallel DBD load linear model, adds measurement capacitance to the discharge load loop, and obtains RC parallel equivalent model parameters by Q-V and I-V Lissajous-Figure analysis. After the experimental data is processed, the simulation circuit model is built by MATLAB/SIMULINK, and the experimental results are compared with the simulation calculation results. They verify the feasibility of the DBD load parameter measurement scheme and comprehensively demonstrate that the DBD load linear resistance capacitance model has important guiding significance in the design of the DBD power supply.
