ABSTRACT:
The present invention is directed to a method and arrangement for controlling a glow discharge plasma in a gas or gas mixture under atmospheric conditions, in a plasma discharge space comprising at least two spaced electrodes in which at least one plasma pulse having an absolute pulse maximum is generated by applying an AC plasma energizing voltage to the electrodes causing a plasma current and a displacement current. The plasma is controlled by providing a relative decrease of the displacement current after the pulse maximum. In a preferred embodiment, the energizing voltage is applied through a series circuit including a choke coil and a non-saturable inductor.
