Dielectric barrier discharges (DBDs) are characterized by electrical measurements interpreted on the basis of equivalent circuits. The concept of the simplest equivalent circuit of volume DBDs is expanded to surface DBDs (SDBDs); this was completed by taking into account the discharge expansion on the dielectric-gas interface. It is assumed, that this expansion is not limited by the dimension of the electrodes. This approach delivers an analytical relationship for the dissipated power as a function of the applied voltage amplitude. It applies to SDBDs with sufficiently long embedded electrodes and operated by sinusoidal high voltages. The obtained relations were validated by comparison with experimental data obtained from previous work devoted to SDBDs with 20mm elongated electrodes operated in ambient air and for applied peak-to-peak voltages of up to 20 kV at 1 kHz frequency. The dependencies derived from the equivalent circuit agree well with experimentally recorded charge and dissipated energy.

介电势垒放电（DBD）的特征在于根据等效电路解释的电气测量。体积DBD的最简单等效电路的概念已扩展到表面DBD（SDBD）。这是通过考虑介电气体界面上的放电膨胀来完成的。假定该膨胀不受电极尺寸的限制。该方法根据所施加的电压幅度提供了针对耗散功率的解析关系。它适用于具有足够长的嵌入式电极并通过正弦高压运行的SDBD。通过与以前的研究数据进行比较，验证了所获得的关系，该实验数据专门研究了具有20mm细长电极的SDBD在环境空气中工作以及在1 kHz频率下施加的最高20 kV峰峰值电压。从等效电路得出的相关性与实验记录的电荷和耗散能量非常吻合。
