英文摘要： Dielectric barrier discharge (DBD) has been widely applied, including ozone synthesizing, low temperature plasma generating and ultraviolet light source manufacturing and so on. In this project, the mechanism model and equivalent electrical model for DBD will be established and the characteristics of DBD load will be analyzed, based on which the appropriate excitation waveform and its parameters are determined, and then a new topology of driving circuit for DBD load will be constructed. ①The spatial and temporal distribution of the electron density, ion density and electric field in the discharge space during gas discharging process will be studied when the local electric field is under balance condition. The ionization and restructuring characteristics of electronics and ionics, and it's the relation with external conditions will be researched. Through the researches, the mechanism model for DBD load, which can descript the process of discharge, and the electrical model for DBD load, which can reflect the process of discharge accurately, are achieved. ②The influences of different excitation waveforms on the dynamic and static characteristics of DBD load will be studied, based on which the constraint relationships among excitation waveform parameters, input-output characteristics of driver and the discharge effi
