APF improve power factor up to 0.99 UL CE CSA


What is APF?

Active Harmonic Filter (APF/STATCOM) is a new active electronic harmonic filtering device  to reduce voltage  harmonic and current  harmonic, improve power factor and improve power quality.

APF Application

• Chemical industry
• Coal mine industry
• Electroplating industry
• Foundry industry
• Forging industry
• Medical industry
• Machinery production
• Commercial building
• Oil drilling
• Papermaking industry
• Steelworks
• Plastics industry
• Textile industry

Dynamic compensation, doesn't depend on system impedance and not easy to happen resonance.

Compensate harmonic and reactive power at the same time.

 Adjust reactive power value continuously, not affected by grid frequency


The other key features of APF are as follows:

l  Design of cabinet integration and modularization

l  Internal structure applies 3H Bridge design and boasts better stable operation.

l  Dynamic response in time: response time100μs and complete response time10ms.

l  Overall efficiency: ≥97% (rated power)

l  Low noise: ≤65dB

l  Harmonic filtration ratio: ≥95%

l  Flexible offset way: amplitude settings can be performed for harmonic offset at each level selected

l  Easy to operate with user-friendly interface.

l  Protection functions for over-current, overvoltage and overheat etc.

l  Auto current limitation, as the output current ≥ the rated, the current will be limited.


Working Principle of APF

Through the external current transformer CT, theAPF detect realtime grid current or load current the controller extract the fundamental current harmonic current through the fast Fourier transform,get active power, reactive power and negat­ive sequence data by the DQ rotation coordinates, generate compensating current into power grid with same value opposite direction as compensating target (harmonic, reactive power, 3 phase imbalance) through IGBT power converter, realize power quality improvement.
