Based on the characteristics of the load for the ozone generator with dielectric-barrier discharge (DBD) method and the inherent resonance problems of the DBD system, a circuit of the power supply for DBD system and its control strategy were introduced and studied.According to the inherent resonance problems of the DBD system, a synchronous control method was adopted to make the resonance progress controllable, so that the hazard brought by the inherent resonance could be avoided.A prototype of DBD ozone generator was made and its control system was also discussed.At the same time, the switch frequency and the efficiency of the power supply of generator were discussed based on the experimental results, and some proposals were given for designing the DBD power supply.The soft-switch function and its effects on power efficiency of the power supply were also discussed based on the prototype.It is verified that the power supply with controllable resonance meets the demands of high-frequency power source of the DBD ozone generator.
