Abstract 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.
