Influence of the dynamics of ions in the admittance of a modulated corona discharge
We present an experimental study of the dynamic impedance in a positive corona discharge that operates as an acoustic transducer. Since the standard equivalent circuits failed to match our experimental results, we considered transit time dependant components. The transit time is determined by the el...

We present an experimental study of the dynamic impedance in a positive corona discharge that operates as an acoustic transducer. Since the standard equivalent circuits failed to match our experimental results, we considered transit time dependant components. The transit time is determined by the elapsed time since a carrier leaves one electrode until it reaches the other. From the equations that describe the dynamics of the ions in the discharge, we found similarities with the behavior of a vacuum diode whose input impedance is mainly determined by the transit time. Based on this approach we were able to match our experimental results with the equivalent circuit by adjusting the transit time, which in turn determines the admittance. The transit time and the direct current density allow computing the carrier density which presents good correlation with the dynamic conductance. This way, we show the method is self-consistent and that the transit time influences the corona discharge input admittance. © 2014 IEEE. |
