• Ozone
• Constant voltage
• Dielectric barrier discharge (DBD)
• Resonant inverter
• Zero current switching (ZCS)

The peak voltage across the dielectric barrier discharge (DBD) type ozonizer is a key factor for ozone synthesis, and it is hard to be kept stable in widely used high-frequency resonant inverters within the entire working range. The soft switching conditions of power switches in these resonant inverters cannot always be satisfied within the entire working range, too. To address the two questions, a new half-bridge high-frequency resonant inverter is proposed in the paper, and the expressions that accurately describe the behavior of the inverter are derived by analyzing different operating modes. The simulation and experimental results show that the peak voltage across DBD type ozonizer is kept stable, moreover, zero current switching of power switches is realized within the entire working range.
