In this paper, a new method to analyse Lissajous figures is developed. The model takes stray capacitance into account, leading to a more accurate equivalent circuit to describe the conditions during a discharge event. Using this method, the external measured current and the relationship between the filament current and the external current can be determined. The model also allows for calculation of the relationship between reduced electric field and ozone efficiency. In this paper, an optimized efficiency of ~207 g/kWh was achieved, at ~123 Td. The relationship between external current and ozone efficiency was also determined by changing gas pressure and barrier thickness. It was found that with increasing barrier thickness and increasing pressure, the ozone efficiency increased, while the external current decreased. The highest ozone efficiency achieved was ~225 g/kWh.
