A prototype HV DC-AC power converter was designed and tested for use on the dielectric barrier discharge(DBD) section of a decoupled thruster on an electro-aerodynamic(EAD) thrust plane application. 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 DBD power characteristics of each waveform. The estimated thrust to DBD power for a sine wave and sawtooth wave were >76% higher than for a pulse wave, and >19% higher than for a square wave, indicating that a sine or sawtooth wave generating circuit such as a SCMLI may be a good choice for EAD flight applications.
