We Make Dreams Fly

Welcome to Electrofluidsystems  

Plasma Generator Systems

Electrofluidsystems, GBS and Megaimpulse are collaborating in the development of high voltage generators for different plasma applications. We distribute single generators and complete starter-packages with power supplies, multi-channel control software and video training for beginners. Please contact us for quotes or look for some special offers in ebay.

Minipuls Series

The compact Minipuls high voltage generators are solid-state control circuit boards with transformer cascades originally developed for unmanned aerial vehicles with onboard plasma systems for flow control or propulsion in 2006-2010. For lab operation, the Minipuls generators can be driven by low voltage regulated power supplies (e.g. 0-36 V, 0-10 A) and are widely used also by customers in the field of dielectric barrier discharge plasma surface and exhaust after-treatment

In the past the Minipuls generators from Minipuls 1 up to Minipuls 6 were all distributed with the logos of Electrofluidsystems as GBS was our subcontracting manufacturer. The first generator types Minipuls 1 and Minipuls 2 are not available anymore but are still in use by many research organizations and universities on four continents. The first customer in 2006 was the USAFA followed by Onera and WPAFB to name a few.

Both Minipuls 1 and Minipuls 2 types had a single integrated board. In 2008, the Minipuls 1 was first changed to MinipulsMini1 and later to Minipuls 0.1. Both the new Minipuls 0.1 and the Minipuls 2.2 listed below have now two separated boards like the more powerful and still available Minipuls 4 and Minipuls 6 generators. 

Minipuls 0.1 - Single-Phase Plasma Generator with 12 kVpp, 5-20 kHz, 30 W, 340 g  (Datasheet)

Minipuls 2.2 - Single-Phase Plasma Generator with 20 kVpp, 5-20 kHz, 140 W, 1160 g  (Datasheet)

Minipuls 4 - Single-Phase Plasma Generator with 40 kVpp, 5-20 kHz, 320 W, 4470 g  (Datasheet)

Minipuls 6 - Single-Phase Plasma Generator with 60 kVpp, 5-20 kHz, 720 W, 8700 g  (Datasheet)

The Minipuls generators can be controlled by standard signal generators or by the following Labview single and multi-channel control software tools in combination with additional National Instruments equipment.

The following MultiPhas 8 and MultiPhasBatt generators were developed during our EHD propulsion research programme for the first 7.5m b-Ionic Airfish (video) from 2004 to 2005 and are still available for purchase. The Minipuls 1 generator mentioned above was derived from the MultiphasBatt in 2006.

MultiPhasBatt - Four-Phase Plasma Generator with 20 kVpp, 6-14 kHz, 240 W, 1100 g  (Datasheet)

DC High Voltage Series 

The DC High Voltage series was also developed for plasma driven airships from 2005-2008. The first HV30kV circuit board with 30kV DC and 45 W was used in the tail cone of the 7.5m b-Ionic Airfish (video). It was later replaced by the more compact and lightweight DC30kVsmd developed for the second 4.5m long plasma airship in 2007 and once more updated in 2017.

The new DC20kVsmd was specially developed for our PLASMA FLYER UAV Systems and is now available for public purchase as well. It is used to induce so-called sliding discharges as shown in our recent oral presentation at the EUROMECH Colloquium 593: PLASMA-BASED ACTUATORS FOR FLOW CONTROL: RECENT DEVELOPMENTS AND FUTURE DIRECTIONS in Delft on 16 March 2018 and later in our poster presentation at the 15th High-Tech Plasma Processes Conference in Toulouse on 6 July 2018.

Nanopuls Series 

Regarding the Nanopuls series we collaborate with Megaimpulse and can also distribute nanosecond high voltage pulse generators to the USA where customers currently cannot directly order from Russia. We usually have better prices than any distributor in the USA and often share some part of our distributor discount with universities and research organizations. Furthermore, we distribute all other equipment from Megaimpulse. Some of them are presently not even officially listed at the Megaimpulse nano website.  

Most of our customers are using NPG-18/3500(N) nanopulser with negative and positive amplitude. We now also distribute the new NPG-18/100k which in basics is a NPG-18/3500(N) with a new 100kHz burst mode as ordered by us for our plasma jet propulsion and by partners working in the field of plasma combustion.
