Dynamic (fast) PFC

Dynamic PFC systems are particularly used in applications with rapid and high load changes. These are automatically regulated systems for central compensation in low voltage distribution boards or for group compensation of sub-systems. 

De-tuned systems for use in applications with non-linear loads i.e. harmonic loads. There are various designs tailor-made to suit your individual application.

This results in the following advantages:

• Improved power quality i.e. high inrush currents from power capacitors are avoided
• The lifespan of PFC systems is increased
• The safety of the full system is significantly increased (i.e. damages due to defective contactors and as a result of exploding capacitors are avoided)
• Extremely rapid regulation of the power factor and therefore consequential reduction of reactive power costs and kWh losses
• Voltage stabilisation (e.g. network support during the start-up phase for large motors)
• Improved utilization for energy distribution (transformers, cable, switch gear etc.) through the elimination of power peaks
• Process times can be shortened (e.g. welding)

Typical applications:

• Illustration: comparison of current and voltage with and without dynamic PFC when starting up a large motor.
• Automobile industry (welding machines, presses...)
• Elevator systems and cranes
• Start-up compensation for larger motors
• Drilling rigs in oil production
• Wind power plants
• Welding
• Steel production
• Plastic injection moulding units
• Fishing boats
