Development of high-voltage high-frequency power supply for ozone generation

A high-voltage high-frequency power supply for ozone generation is presented in this paper. ozone generation is intended to be used in air and in water disinfection. a power stage consisting of a single-phase full bridge inverter for regulating the output power,a current push-pull inverter (driver) and a control circuit are described and analyzed. this laboratory build power supply using a high voltage ferrite transformer and a pic microcontroller was employed to energize a dielectric barrier discharge (dbd) ozone generator. the inverter working on the basis of control strategy is of simple structure and has a variation range of the working frequency in order to obtain the optimal frequency value. the experimental results concerning electrical characterization and water treatment using a cylindrical dbd ozone generator supplied by this power supply are given in the end. © school of engineering,taylor’s university.
