Matching a pulsed power modulator to a corona plasma reactor

In this paper, the matching between the a pulsed power modulator and a corona plasma reactor is discussed. The matching is expressed as the energy transfer efficiency between the modulator and the reactor. The criterion for optimal matching between a source and a load is that the output impedance of the source is equal to the load impedance. When trying to match a pulsed power modulator to a plasma reactor this criterion is difficult to obey since the load impedance changes rapidly before, during and after plasma generation. To simulate the response of the load as function of the voltage pulse, an equivalent circuit is used. Measurements will be presented to verify the derived model. Guidelines to optimize the matching between the modulator and reactor are derived.
