电荷电压法测量DBD等离子体的放电参量

在DBD应用研究中，使用电荷电压法能够测量许多重要参量，如放电功率、放电间隙等效电容、电介质层等效电容、着火电压、放电间隙等效电压及放电间隙电场强度等．同时根据电荷电压图形随工作条件及状态变化的情况还可以诊断DBD等离子体的工作稳定性．文章对相关原理、模拟实验结果及实际应用效果进行了介绍．

Electrical characterization of dielectric barrier discharge plasma using the charge-voltage figure

With the charge-voltage figure many key parameters may be obtained for studies on the applications of dielectric barrier discharge (DBD)plasma, such as the discharge energy, gap capacitance, dielectric capacitance, cut-in voltage, gap voltage, and discharge gap electric field. At the same time the stability of DBD plasma can be diagnosed by the charge-voltage figure which changes with changes in the operation conditions. The underlying principles, experimental simulation results and actual application developments are des- cribed.
