Cold Plasma Generator Using Economical High-Frequency High Voltage Flyback Transformer With Straight and L-Shaped Needles

Abstract

Cold plasma has long been recognized for its effect which can be used to inactivate viruses and bacteria, both on objects and in the air. In the current state of the coronavirus pandemic, economical plasma generators can play a role in medical handling and room sanitation needs. This study analyzes the use of an inexpensive high-voltage flyback transformer that is easily available in the market and makes use of it to produce a compact cold plasma generator. The flyback is tested by conditioning the frequency variations with the same pulse width. The test results showed variations in the output voltage and ion quantity. The variation of the ionizing needles used also showed that the L-shaped needle produced an anomalous increase in the peak of ions at its best resonance. However, the ions in the L-shaped needle is slightly lower when compared to the variation of the straight needle at the other frequencies.
