“…Fig.9.b) shows the comparison for R p . With increasing frequency, R p decreases; this trend is consistent with results published in [19]. The deviations in the extracted and experimental values of C p and R p may be due to the following reasons: (1) the variable inductor values used in the experiment are not the same as those obtained from extracted results.…”

In order to design an efficient resonant power supply for ozone gas generator, it is necessary to accurately determine the parameters of the ozone chamber. In the conventional method, the information from Lissajous plot is used to estimate the values of these parameters. However, the experimental setup for this purpose can only predict the parameters at one operating frequency and there is no guarantee that it results in the highest ozone gas yield. This paper proposes a new approach to determine the parameters using a search and optimization technique known as Differential Evolution (DE). The desired objective function of DE is set at the resonance condition and the chamber parameter values can be searched regardless of experimental constraints. The chamber parameters obtained from the DE technique are validated by experiment.

“…In [10]- [14], a voltage-fed full-bridge resonant inverter with high-frequency inductor is proposed. The inductor is placed at the secondary [13], [14] or primary [11] side of the transformer to stabilize the discharge in the ozone chamber. In [15], a current-fed full-bridge inverter which employs a parallel inductor between the secondary and the ozone chamber is implemented.…”

Abstract-This paper describes the analysis and design of an LCL resonant power supply for ozone generation. The main advantage of the proposed topology is the absence of high-voltage transformer; the high voltage gain is achievable by means of doubleresonance phenomena. Furthermore, the bandwidth is wider than the ordinary LC and its phase difference is constant over specific frequency range; as a result, an open-loop operation can be implemented. The complete analysis and design procedure of the power supply is presented. The design procedure is verified by implementing the power supply to drive a dielectric barrier discharge prototype ozone chamber. The hardware results are found to be in close agreement with simulation and thus justify the validity of the design procedures. The proposed circuit is suitable for portable ozone power supply fed by low-voltage source such as battery or photovoltaic module.Index Terms-Dielectric barrier discharge (DBD), full-bridge inverter, high-voltage power supply, LCL resonant circuit, ozone generation.

“…In these circuits, the inductance is placed at the secondary of the transformer to stabilize the discharge. In [14]- [17], a full bridge inverter using a resonant inductor at the primary side is used to reduce the tuned resonant frequency. For both cases, the presence of the inductor increases the complexity of the circuit and reduces its efficiency.…”

It is known that transformer based power supplies for ozone generators have low efficiency, high cost and exhibits a limited frequency range of operation. To overcome these disadvantages, this paper proposes a high frequency ozone generator with the absence of a transformer. The voltage step-up is achieved only by utilizing the resonant tank. This is made possible by a novel combination of ozone chamber materials that allow ozone to be generated at only 1.5 ̶ 3.5 kV p-p . The input to the resonant tank is driven by a PWM full bridge resonant inverter. Furthermore, zero-current zero-voltage switching (ZCZVS) operation is achieved by employing a duty factor of 25% between the switches of the full bridge. The advantages of the proposed system include high efficiency, low cost and the ability to control ozone production by varying the input voltage to the inverter. The prototype is verified by both simulation and experimental results.
