The DBD（Dielectric Barrier Discharge）type ozonier powered by full bridges series resonant inverter in capacitive control is studied in detail in the paper. By analyzing the on-off conditions of the power switches and the states of discharge and no discharge of DBD circuit, the working modes of power supply are achieved in capacitive control and some correlative expresses are deduced. Based on these expressions, the highest voltage of DBD circuit, the working frequency of inverter and the discharge power of DBD circuit are given. The error analysis of working frequency of inverter and the highest voltage of DBD circuit are made based on the theoretical calculations and experimental results. These expressions in the paper are validated by the results of error analysis. In addition, the regulating characteristics of power supply are analyzed. Compared with other control strategies, there are lots of merits in power supply for DBD circuit in capacitive control, such as small frequency fluctuating, big output power and being convenient for control and so on. The conclusions in the paper is helpful to designing the power supply powered by full bridges serial load resonant inverter for DBD type ozonier, and the analytic method of working modes in DBD circuit is suitable for other control strategies in serial load resonant power supply for DBD type ozonier.
