Transformerless power supply based on single switch resonant inverter for ozone generation

Abstract

This work proposes a transformerless power supply for ozone generation, based on single switch resonant inverter. It is used in conjunction with a LC resonant circuit to achieve high voltage (up to 4 kV) that provides sufficiently high voltage to break the oxygen molecule. Furthermore, the dielectric of the chamber is constructed using muscovite mica that allows for a lower initiation voltage. Due to the absence of the transformer, the system has a smaller footprint and more efficient. A prototype ozone generator is constructed and typical results are presented. It is found that the ozonizer draws very little power, i.e. less than 8 W with very high ozone yield (over 120 g/kWh at 1.0 L/min).
