Minipuls Series

The compact Minipuls high voltage circuit boards are sophisticated solid-state high voltage coil cascades originally designed for unmanned flight systems using plasma actuators for flow control or propulsion. For lab operation (e.g. plasma surface treatment), the Minipuls circuit boards can be driven by regulated low voltage power supplies (0-36 V, 10 A or 0-36 V, 20 A).

For newcomers and unexperienced groups, Electrofluidsystems offers starter-kits including 2 Minipuls generators, 2 regulated low voltage power supplies, 1 high voltage probe with BNC connector, plasma actuator material (tinned copper foils with up to 50.8 mm x 16.46 m, Kapton tapes with up to 25 mm x 33 m), 10 m Teflon insulated high voltage cable, National Instruments equipment (NI-PCI-6711/13/15, SH68-68-EP cable (2m), BNC-2110), 2-channel-control software programmed with Labview 7.1, Training via video sessions for technology and know-how transfer where the customer will "plug" the system together with us and start to "play" like an experienced professional.

This is the polyphase generator which was used in the b-IONIC Airfish in 2005.



Software:  Multi-Channel Control Software for Minipuls and Multiphasbatt

Several Minipuls generators (e.g. up to 8 using the analog output NI-PCI-6713) can be used to drive plasma phased arrays with a multi-channel control software based on Labview 7.1 (see below) which enables changes for the phase angles between carrier and modulation frequencies. To study quasisteady and unsteady electrostatic traveling waves, there is need for at least 2 Minipulse generators. To generate computer-controlled nonlinear electrostatic waves (plasma solitons) by harmonic or anharmonic wave mixing, there is need for 4 Minipulse generators.

DCPower Series

The compact DCPower high voltage circuit boards are sophisticated solid-state high voltage cascades originally designed for unmanned flight systems using plasma actuators for flow control or propulsion. In constant DC mode the generators can be used to induce corona discharges from wires or to support sliding discharges in combination with a Minipuls generator. In pulsed DC mode the circuit board can be used to induce dielectric barrier discharges or field electron emissions from high-k materials. These boards can also be used for surface plasma treatment and electrospinning applications. The DCPower circuit boards are driven by an external power supply with 36 V.

Why nanopulse high voltage generators for flow control?

This is based on a speculative but exciting idea by Dr. Ernest Okress:

1. Ernest Okress (1967) Crossed Field Plasma Device. US3355605.

2. Ernest Okress (1968) Air Blower. US3374941.

3. Ernest Okress (1968) Fluid Mover. US3396662.

4. Ernest Okress (1969) Quasi-Corona Aerodynamic Vehicle. US3464207.


The idea was revived in 2006 by scientists from Princeton University:

1. A.V. Likhanskii, S.O. Macheret, M.N. Shneider, and R.B. Miles (2006) Modeling of Interaction Between Weakly Ionized Near-Surface Plasmas and Gas Flow. AIAA-2006-1204, 44th AIAA Aerospace Sciences Meeting and Exhibit, Reno, Nevada.

2. A.V. Likhanskii, M.N. Shneider, S.O. Macheret, and R.B. Miles (2007) Optimization of Dielectric Barrier Discharge Plasma Actuators by Repetitive Nanosecond Pulses. AIAA-2007-633, 45th AIAA Aerospace Sciences Meeting and Exhibit, Reno, Nevada.



These ideas are only interesting in combination with high-k (high dielectric strength) materials based on ferroelectric dielectrics. TU Berlin is working on these issues since 1988. Nanosecond high voltage switching is necessary to induce powerful field electron emissions from ferroelectric materials.


The high-k dielectric barrier discharge from ferroelectrics were pioneered by Dr. Hartmund Gundel (TU Berlin, Germany), Prof. Jan Handerek (Uni Silesia, Poland) and Prof. Kazimierz Biedrzycki (Uni Opole, Poland) in the late 80s and early 90s. Today, it is possible to develop ferroelectric dielectrics with a high-k of 100,000 and more. The high dielectric constant of ferroelectric ceramics is necessary to cause considerable field enhancement at triple junctions. These are regions where tunnelling field emission of electrons starts and leads to surface plasma formation. With high-k (high electric permittivity) materials, it is possible to get higher plasma induced neutral air velocities with smaller voltages.
