Optimization of Ozone Generation by Investigation of Filament Current Characteristics Under Dielectric Barrier Discharge

In this paper, the relationship between reduced electric field and ozone efficiency was determined between ~120 and 280 Td, with an optimized efficiency of ~207 g/kWh at ~123 Td. An equivalent circuit with stray capacitance was used to analyze the filament current in the barrier discharge. The statistical distribution of the filament currents was found to change with different conditions, observing decreased mean amplitude and a narrower distribution with increased pressure and barrier thickness. Under the same reduced electric field, higher ozone efficiency was achieved at a lower current and narrower distribution.
