摘　　要： 介质阻挡放电(DBD)型臭氧发生器工作时存在放电和未放电两个模态,因而其电源的设计非常繁琐。本文分析大量试验数据后发现,DBD型臭氧发生器上电压峰值与流过发生器的电流峰值和逆变电路的输出功率基本符合线性变化规律。基于这一特性,本文提出了臭氧发生器的一种线性化的等效模型,将它等效为与功率相关的电阻和容抗串联电路。并用此模型对主回路进行了分析计算,给出其设计方法。与其他方法相比,本文提出的主回路参数设计方法具有设计步骤少、计算简单和无需考虑DBD电路参数变化等优点,可为工程中分析和设计臭氧发生器供电电源提供参考。实验结果验证了本文推导的正确性。 There exit discharge mode and non-discharge mode in dielectric-barrier discharge （DBD） type ozonizer, so it is very difficult to analyze and design the power supply for ozonizer. By analyzing experiment results, it is founded that peak voltage and peak current of ozonizer is basically proportional to output power of inverter. Based on the proportional relationship, an equivalent model of DBD type ozonizer is presented in the paper. The model is composed of a resistance and capacitive impedance. With the model of ozonizer, the power supply for DBD type ozonizer is analyzed and the design method is achieved. Compared with other design methods, the design method has less design steps, more simple calculation and is not necessary to deal with fluctuant parameters of ozonizer. The design method will be helpful for analyze and design power supply for ozonizer in industrial application. Experiment results validate the equivalent model and conclusions.
