The development of ozone generation with low power consumption

Abstract

This paper proposed the use of low power and low cost high frequency, high voltage resonant inverter as power supply to produce ozone gas at normal atmospheric pressure and ambient temperature. The modified class E resonant power converter is studied based on modified boost converter. The advantage of resonance phenomena used to convert the square waveform voltage input into sinusoidal output voltage in high voltage and high frequency. The model of the ozone chamber is developed using the RLC circuit. This basic RLC resonance tank circuit is used to determine the resonance frequency for inverter as a power supply to ozone chamber. It is also investigated the use of class E resonant when it is operated below resonant converter and act as pulse converter to supply the ozone chamber. As the result, the class E resonant converter has successfully produced maximum 2.8 kVpp, 8.66 kHz as resonant converter consumed of 8.74 Watt to produce 11, 300 µg/m3 ozone. As the pulse power supply, the class E circuit produced 2.8 kVpp at 6.2 kHz, 18.3 watt to generate 5, 900 µg/m3 Ozone. This low power converter and simple ozone chamber has a possibility to be developed as ozone generator system in compact form for residential application.
