VARSine ActivSine - Active Harmonic Filter

The ActivSine series active harmonic filter operates on a three-level topology circuit. It provides power quality solutions such as harmonic elimination, real-time automatic power factor correction, and load balancing. It is available in three versions: a wall-mounted enclosure version, ranging from 30A to 150A, a rack-mountable version for standard 19” cabinets, ranging from 30A to 150A, and a cabinet version, ranging from 100A to 600A.

Its modular design allows users to easily achieve the desired filter current capacity by connecting up to 20 modules in parallel.

• Fast compensation of harmonics and reactive power,
• Elimination of 3rd order harmonics and multiples of 3 (triplens), reduction of current in the neutral
• Data centers and UPS systems
• Renewable energy production installations (photovoltaic and wind)
• Industrial production machines with frequency converters
• Resistance welding workshops (electric)
• Industrial machines for plastics: extrusion machines, injection molding presses, etc.

• Maximum safety and reliability
• Overload Protection
• Protection against internal short circuits
• Overheating protection
• Protection against overvoltage and undervoltage
• Protection of power electronics components
• Protection against resonance
• Fan fault alarm

• The active harmonic filter operates on a three-level neutral point clamped (NPC) topology. As shown in the figure below, the traditional structure of the 2-level topology circuit consists of 6 IGBTs (2 IGBT power devices on each phase pin and current path), and in the 3-level topology, there are 12 IGBTs (in each phase, 4 IGBT power devices on the pins and current paths).

• The three-level topology circuit can generate three voltage levels at the output, including the positive DC bus voltage, the zero voltage, and the negative DC bus voltage. Two-level topology circuits can only produce positive and negative voltages. At the same time, the three-level topology circuit also ensures higher quality output voltage and better harmonics, thereby reducing requirements for output filters and associated costs.
