Description

Recently, the development of atmospheric pressure non-thermal plasma has been the research interest of many research groups world wide. This is because it is now realized that there is a need to develope cost effective plasma technology so that it can be more widely used in industry. The atmospheric pressure plasma devices being considered include the glow discharge and the dielectric barrier discharge. Besides reducing cost by working with atmospheric pressure, another cost factor is the power supply. Currently, RF or microwave sources are commonly used in industry to power the plasma system. For the generation of non-thermal plasmas, it is suitable to use the 50 Hz household supply to power the glow discharge or the dielectric barrier discharge. A step-up transformer can be used to provide a discharge voltage higher than the 240 V peak voltage supply from the mains.
