APLIKASI IGNITION COIL SEBAGAI PEMBANGKIT TEGANGAN TINGGI IMPULS UNTUK PENYEDIA DAYA REAKTOR OZON

Abstract

Ozone can be made by passing oxygen gas (O2) in areas subjected to high voltage. Oxygen molecular (O2) that are subjected to high voltage will be ionized, that is an atom or molecule releasing process from its binding to oxygen ions (O *). The types of oxygen ions (O *) can be O+, O2+, O-, O2-and O3-. The combination of all of which can produce ozone(O3). In this final project, designed high-voltage impulse generator using the ignition coil and DC chopper type buck as the power supply. Ignition coil is choosen because of it’s small normally-voltage, that is 12 V, but the output voltage can reache 20kV of impulse voltage. To supply the variable voltage, used DC chopper beacuse physically lighter and smaller than variac in general. So that the tool can be more portable. Tests for ozone identification using the decolourization methode using needle-broad ozone reactor. Based on the experiment’s result it’s known that the impuls high voltage can be generated from this tool are variable between 5-20 kV. The higher the voltage generated, the faster decolourization process. And at voltage 20 kV, absorbance has decreased significantly from 0, 517 to 0.094 (82 % decreased) in 10 minutes.
