Analysis and Assessment of Use of Voltage and Current Inverters Applied to the Ozone Generation in High Frequency

The study of this article mainly focuses on the assessment and performance of current and voltage inverters in ozone generation, applying power density modulation (PDM) and typical operation. The topologies designed were a voltage-source full-bridge inverter (VSFBI), a current-source full-bridge inverter (CSFBI), and a CSFBI without considers the PDM. The inverters were analyzed and implemented considering an inductor-capacitor-capacitor (LCC) series-parallel resonant tank for the VSFBI and an LC parallel resonant tank for the CSFBI. The duty cycle impact ( D_{\mathrm{ m}} ) of the modulation signal was analyzed, and all inverters were compared. Based on the results, the decrease in D_{\mathrm{ m}} allows increasing the ozone generation because of avoiding the dissociation of the ozone molecules. The maximum concentration and efficacy presented by the VSFBI in ozone production were 620 gr/m 3 and 0.155 gr/min. Also, the maximum electrical efficiency was 91%; it was presented by the CSFBI without PDM.
