摘　　要：为了研究稳态工作时的介质阻挡放电(DBD)型臭氧发生器的等效模型,以采用串联谐振逆变电源供电的、所产生臭氧的质量流量为1kg/h的介质阻挡放电型臭氧发生器为研究对象,通过实验数据和曲线拟合相结合的方法对臭氧发生器的等效电阻、等效电容与发生器的放电功率进行了研究。研究结果表明,稳态工作时的臭氧发生器可由与放电功率成线性关系的电阻和电容串联构成等效模型来表示。基于这一等效模型,对移相控制下的串联谐振式DBD型臭氧发生器供电电源特性进行了分析。分析结果表明,由所提出的等效模型和供电电源特性分析方法得到的结果与实验结果具有较好的一致性,可用来解决臭氧发生器供电电源设计繁琐的问题。In order to study the stable equivalent model of dielectric barrier discharge （DBD） type ozonizer. A set of ozone generator system which eouid produce 1 kg ozone per hour was tested and the ozonizer was powered by serial load resonant inverter. By analyzing the experimental data and using curve fitting method, the relationship among the equivalent resistance, equivalent capacitance and discharge power was researched. The research results show that the equivalent model of DBD type ozonizer is composed of an equivalent resistance and an equivalent capacitance. The equivalent resistance and equivalent capacitance were proportional to discharge power. Based on the equivalent model, the performance characteristics of serial load resonant power supply with a kind of phase-shift control strategy for ozonizer was analyzed. The analysis results show that the equivalent model and the performance characteristics of power supply are well fitted with the experimental results. The equivalent mode and analysis method of power supply characteristics can be used to solve the complex process of power supply design for DBD type ozonizer.
