On the use of switched-capacitor multi-level inverters for electro-aerodynamic thrust applications
… The converter was a switched-capacitor multi-level inverter(SCMLI) capable of generating a variety of AC waveform shapes. The power draw of the DBD and the DC corona discharge current were measured for each waveform at a DBD voltage of 6kVpp and 10kHz, and used to estimate the thrust to …
