Yanfei Zhu · Gao dianya jishu · 2009
In order to decrease measurement error of the common voltage-charge lissajous figure measurement method for dielectric barrier discharge(DBD)circuit,based on the original equal circuit of DBD circuit,some constraint equations of lissajous figure measurement method are deduced.With the equations,it is proved that,if the effect of measurement capacitance is neglected,the measurement value of barrier capacitance is larger than the true value and sustain voltage has inherent error.In order to solve the question,a new type of measurement method is presented.In the new measurement method,measurement capacitance is independent of the main circuit,so the measurement method can not only solve the inherent error by common lissajous figure measurement method but also isolate measurement circuit with main circuit.Thereby,the new type measurement method has lots of merits,such as accurate measurement,easy wiring,low measurement workload,et al.The experimental results verify the improved measurement method.
