High Density Ozone Generation System Using Fuzzy Inference Engine

Abstract:

Ozone (O₃) is generated by voltage control inverter of single phase sinusoidal waveform different from current control inverter of three phase used in motor control. Ozone quantity is directly proportional to the frequency as well as the voltage of power supply. In this paper, we propose not only a voltage control inverter of 600Hz and step-up transformer from 220V to 12KV using IGBT, but also fuzzy inference engine using MADANI Min-Max composition so as to generate the high density ozone generation. We substantiate that the proposed Ozone generation system produces the double quantity of ozone and higher efficiency than conventional ozone system using the current control inverter through lots of real experiments on the developed ozone system.
