Impedance matching for an asymmetric dielectric barrier discharge plasma actuator

A typical dielectric barrier discharge plasma actuator requires a power supply capable of delivering power at a frequency range of several kilohertz and a rms voltage up to 20kV. An impedance mismatch resulting from the absence of a matching network causes a large reflected power from the plasma actuator back to the power supply. This does not contribute to plasma formation and requires an expensive over-rated power supply. The authors suggest an impedance matching network for a realistic asymmetric dielectric barrier discharge plasma actuator with a virtual electrode.
