Active Harmonic Filter
Many industrial grid appliances such as inverter, rectifier, it may be commercial or public buildings with the electrical grid to extract non-sinusoidal current from the grid. Non-sinusoidal current consumption resulting in perturbation of the electricity network, which said harmonic load.
High harmonic current of serious consequences arising
The cables, power distribution equipment and transformers produce additional heat loss resistance
Changing the voltage waveform, interfere with the normal power other electrical
Network load caused by asymmetric
Resulting in rapid aging and the use of electrical power facilities
Resulting in large-scale distribution system overload devices may cause a fire or damage to the instrument

Use industry
Rapid changes in load (subway locomotives, welding machines, factories traffic, etc.)
High power quality requirements of the high-tech industries (precision electronics manufacturing, aerospace industry, automobile industry, etc.)
Large-scale civil construction, financial centers, computer centers, communications room, high-tech stadiums
Response time of less than 1ms, fast response, high precision control
Not affect the filter characteristic impedance of the system, you can eliminate the risk of the occurrence of the resonant impedance of the system;
Adaptive function that automatically compensate for changing track harmonics.
