  This work presents a simple power converter, without any high voltage
transformer, able to supply and control a plasma jet based on dielectric
barrier discharge. The converter, operating in pulsed current mode, requires a
single power switch and is fed by a low voltage DC source. It can deliver very
short duration pulses to the plasma jet with high current amplitude. The
operating principle is explained by means of the state plane analysis and is
validated with simulations and experimental results. The equations provided
allow for the calculation during the design stage of important characteristics
of the plasma jet as the peak voltage and the duration of the pulses. The power
can be easily adjusted during experimentation to comply with the desired
appearance of the plasma jet.
