Load model and parameter measurement method of DBD for power supply design

Abstract Plasma is widely used in sterilization and disinfection, environmental treatment, material surface modification. At present, the DBD load equivalent circuit model design of dielectric barrier discharge (DBD) low-temperature plasma generator power supply mainly includes nonlinear clamping linear resistance capacitance model, which have advantages disadvantages research application load. This paper focuses on modeling parameter acquisition method RC parallel adds measurement to loop, obtains parameters by Q-V I-V Lissajous-Figure analysis. After experimental data processed, simulation built MATLAB/SIMULINK, results are compared with calculation results. They verify feasibility scheme comprehensively demonstrate that has important guiding significance supply.
