Abstract :
In this study, we investigated a water treatment method that sprays waste water droplets into pulse discharge space. It is important for this method to apply pulsed voltage of a short pulse width and a fast rise time to the electrode to realize high energy efficiency. Inductive energy storage (IES) circuit using a semi-conductor opening switch (SOS) realizes pulsed voltage like that. The water treatment using that circuit was carried out. Initially, the maximum of current of the SOS was varied without changing the pulse width by varying capacitance and inductance. As the result, the energy at the discharge load increased for larger current of the SOS. Pulse width of the voltage and the energy transfer efficiency were not influenced by difference of current of the SOS. Then, the pulse transformer (PT) turn ratio and the capacitance were changed. The energy at the discharge load was higher at the turn ratio of 2:22, and the energy transfer efficiency was improved from 6.8% to 19.2%. The indigo carmine decomposed at quicker rate under the larger discharge condition.
