Since the amount of ozone produced is affected by temperature and humidity, The measurement was performed at a temperature of 20 ° C and a humidity of 65%. In addition, since the high-voltage power supply boosts and rectifies a commercial AC power supply to generate a DC high voltage, an AC component (ripple) may remain in the high-voltage power supply waveform. When the ripple is large, local short circuit (spark) increases between the discharge electrode plate and the ground electrode plate. In this example, a high voltage power supply with a ripple size of 5% (effective value) or less was used.
