ABSTRACT

The electrical characteristics of a filamentary dielectric barrier discharge (DBD) are studied experimentally and numerically. The DBD system which has parallel plate electrodes geometry is powered by a 50 Hz power supply and operated at atmospheric air. A dynamic electric circuit model considering the discharge region and the non-discharge region being connected by a surface resistance is proposed. Simulation using this model is shown to fit the experimentally measured QV diagram satisfactorily. The effects of the air gap distance and the dielectric surface on the discharge behavior are then investigated. It is found that the surface resistivity of the dielectric is one of the important parameters governing the discharge behavior.

ABSTRAK

Ciri nyahcas dielektrik berpenghadang (DBD) telah dikaji secara eksperimen dan berangka. Sistem DBD yang mengandungi dua elektrod plat yang selari dikuasakan dengan bekalan kuasa 50 Hz dan beroperasi dalam udara atmosfera. Satu model elektrik yang mengambil kira rantau tidak bernyahcas dan rantau bernyahcas telah dicadangkan. Dalam model elektrik ini, rantau tidak bernyahcas dan rantau bernyahcas disambung dengan satu rintangan permukaan. Keputusan simulasi berjaya menyamai keputusan Lissajous QV yang diperoleh daripada eksperimen. Kesan jarak jurang ruang dan rintangan permukaan dielektrik dalam DBD juga dikaji dan didapati bahawa rintangan permukaan dielektrik adalah satu parameter yang penting untuk mengawal sifat nyahcas.

 

Kata kunci: Ciri elektrik; nyahcas dielektrik berpenghadang; nyahcas filamen; model elektrik
