AFS Generators in detail
With over 40 years of experience, AFS generators are among the best-selling in the world. They guarantee reliable and efficient power supply for your Corona treatment stations and Dielectric Barrier Discharge (DBD) reactors thanks to the highest quality and safety standards. Benefit from maximum availability, intuitive operation, and optimal process integration. Rely on the market leader for maximum process reliability and efficiency.
Function of AFS generators
AFS corona generators are THE standard in the film extrusion and packaging industry. They stand for constant innovation, high flexibility, and robustness. The entire design is geared toward combining maximum availability with efficiency and user-friendliness. All generator types are based on the same high-quality technology that AFS has developed and continuously improved over many years. They always operate at resonance frequency, ensuring a long service life with maximum energy efficiency.
Highest quality, reliability, and efficiency make AFS generators the industry standard.
The use of proven AFS generators is not limited to the surface treatment of web materials (known as Corona treatment). They are generally suitable for operating plasmas. AFS has thus specialized as a manufacturer of high-quality and scalable power supplies for DBD (dielectric barrier discharges) and gliding arc discharges for various applications, including plasma chemistry.
Special applications and research
In research and development the requirements for generators differ from daily operation in production plants. Providing full parameter flexibility while at the same time offering a high level of reproducibility, the AFS research generator has been specially developed for the use in the laboratory.
During many years of close collaboration with leading research institutes in the field of plasma, AFS has developed a power supply, the research generator G05F, with which every parameter of a dielectric barrier discharge (DBD) can be optimally adjusted and analysed. Particular attention was paid to easy to manage interfaces to integrate modern time resolved diagnostics into the process. The generator, and thus the plasma can be triggered internally or externally according to the particular requirement of the experiment.
The result is maximum control over the plasma process while maintaining complete flexibility in interaction with the surrounding laboratory. The G05F represents the successor of the successful generators G05S-150k, G05S-500k and G10S-V. As soon as a plasma process is successfully developed and tested and thus ready for subsequent scale up in industry, AFS has the exactly fitting instruments.
The proven power supplies from Corona treatment provide the perfect means for such industrialisation. Any parameter or mode of operation, that is feasible using the G05F, is realizable using the standard portfolio of AFS power supplies, respectively Generators. Do you have a special project in mind?

Application examples
M-Series
Top line of AFS high-voltage generators. The AFS generator of the M series represents the latest available technology in high-voltage generators for a power range of 6 – 144 kW. The failure of one module does not mean a system shutdown, but only a reduction in output power (depending on the power of the module). The ability to combine modules makes it possible to manufacture generators with almost any output power.
P-Series
The AFS P generator was developed specifically for gliding arc discharges. It enables reproducible and controlled operation of pulsed plasmas without a dielectric. It is known for its use with the PlasmaJet®.
S-Series
Extensive standard equipment, all possible options available. Proven thousands of times over. Power range from 500 watts to 60,000 watts.
M2-Series
Dual generator based on the M series. The M2 generator contains two independent inverters (individually controlled outputs) that share a power supply and housing. Advantage for double-sided applications: consistently identical treatment results on both sides thanks to its two regulated outputs. Easy operation, low space requirements, and affordable price make this generator the superior choice compared to single generators. Power range from 2x 3 to 2x 36 kW.
SE-Series
Top electronics in an economical package. All important functions as standard, many useful options available. Power range up to 12 kW.
System overview G05F
AFS generators for maximum production reliability and productivity
- Control of the coupled power directly via primary voltage and excitation frequency, alternatively via the measured secondary-side high-voltage amplitude or classically directly via the output power, as in the “normal” corona process. This allows process parameters to be precisely approached and then maintained constant for hours and days, regardless of heating effects in the reactor or transformer. Even sensitive test setups that can only tolerate a few watts or low voltages can be operated safely. Power range: 5 to 1000 W.
- Analog inputs (BNC) for controlling all control variables via analog voltages (0 .. 10 V).
- Analog outputs (BNC) for recording process variables on your own oscilloscope.
- Active pulse function with pulse length and pulse pause settings directly on the generator's touchscreen. The smallest selectable pulse length is a single sine wave.
- Passive pulse function via external triggers. The generator adjusts its switching on and off to the external system clock.
- In burst mode, an internal or external trigger signal triggers a number n of sine waves selected on the generator, after which the generator waits for the next trigger pulse (n = 1 .. 65000).
- Adjustable spark gap for safe operation and effective protection against overvoltages.
