Plasma Ozonizer Using Micro-Converter for Ammonia (NH3) Decreasing in Shrimp Food Production

This paper presents design of plasma ozonizer using high voltage high frequency in micro-converter for Ammonia (NH3) decreasing in shrimp food smell. This supply uses flyback converter at 1.5 kVP, 30 kHz and controls its operation using pulse width modulation (PWM) techniques. Power MOSFET#IRFP460 is controlled by IC#TL494. The highly nonuniform electric field electrode tube of two level insulator cylindrical. The testing of plasma ozonizer using high voltage is 1.5 kVP, which ozone tube enables ozone gas generating capacity of 93.6 mgO3/hr which effectively decrease Ammonia (NH3) from 4.07 ppm to 2.15 ppm in shrimp food production.
