Active Power Filter is a new electric power harmonic management dedicated device, which adopts modern power electronics technology and the digital Signal processing technique in the Digital Signal Processor (DSP). This Filter can overcome the traditional Filter, like LC Filter etc. Shortcomings of harmonic suppression and reactive power compensation, achieve dynamic tracing compensation and fill the harmonic, reactive power. The main function is managing the current harmonic, Series active Filter is mainly managing the voltage harmonic.

Active Power Filter is widely applied for industry, commerce and organizations in power networks. Example, electric system, water treatment equipment, petrochemical enterprise, huge mall and office building, precision electronic enterprise, airport/port power supply system, medical institutions. According to different application object, active filter can  ensure power supply reliability, reduce the interference and improve the product quality, increase equipment life, reduce equipment damage, and so on.

Advantages and features:

1. >97% work efficiency, low loss and green energy saving.

2. Filter from 2th to 50th times harmonics simultaneously, or Selection of every harmonic from  2th to 50th times harmonics.

3. Reaction time<100μs, response time<10ms.

4. Active filter range is from 25A to 600A

5. Available in modular designs and complete cabinet type

6. Selection of specific times harmonic suppression.

7. Reactive power compensation and unbalanced load etc. three model.

8. Adopt 3DSP+CPLD full digital control mode, filter out harmonic precisely.

9. 3-level topology inverter circuit Fast Fourier Transform (FFT) and instantaneous reactive power two calculation methods.

10. Modular design, the system is stable, affordable - 40% ~ + 40% voltage fluctuation, better quality, reduce system’s single fault points, parallel flexibly, and to adapt to different working conditions
