A Model Parameter Extraction Method for Dielectric Barrier Discharge Ozone Chamber using Differential Evolution

Abstract

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.

A proposed optimized equivalent circuit and performance analysis of dielectric barrier discharge ozone generator

“…The two main objectives of parameters determination of dielectric barrier discharge dielectric barrier discharge (DBD) ozone generator are to find exactly the resonance frequency and the voltage gain of the entire system [1]- [3]. The design of the DBD ozone generator power supply is basically depending on this frequency [4]- [9].…”

“…These parameters of DBD ozone chamber can be determined using one of these two techniques; Lissajous plot or differential evolution (DE) method. Lissajous plot achieves good results in frequency range (15-20 KHz) [25][26][27]. This is attributed to the plotting shape which will be distorted outside this frequency range.…”

“…Differential evolution (DE) technique, on the other hand, depends on the resonance frequency. This means that as the resonance frequency increases, accuracy of parameter values will be enhanced [25][26][27]. In this work, DBD ozone chamber parameters will be extracted from measuring of high voltage and current waveforms which applied to DBD ozone chamber.…”
