-Product Description


?Active harmonic filters (AHF) are the ultimate answer to power quality problems caused by waveform distortions,

low power factor,voltage variations,voltage fluctuations and load unbalance for a wide range of segments and applications.


?They are a high performance,com-pact,flexible,modular and cost-effective type of active power filters (APF) 

which provide an instantaneous and effective response to power quality problems in low or high voltage electric power systems.


?They enable longer equipment lifetime,higher process reliability, improved power system capacity and stability,

and reduced energy losses, complying with most demanding power quality standards and grid codes.

?AHFs eliminate waveform distortions from the loads like harmonics,inter harmonics and notching,and harmonic voltages caused by harmonic currents,

by injecting in real time the distorted current of same magnitude but opposite in phase in the electric power system.

In addition, AHFs can take care of several other power quality problems by combining different functions in a single device.

〓   Working Principle   〓


?External CT detects the load current,DSP as CPU has advanced logic control arithmetic,could quickly track the instruction current,

divides the load current into active power and reactive power by using the intelligent FFT,and calculates the harmonic content rapidly and accurately.

Then it sends PWM signal to internal IGBT's driver board to control IGBT on and off at 20KHZ frequency.

Finally generates opposite phase compensation current on inverter induction,at the same time CT also detects the output current 

and negative feedback goes to DSP. Then DSP proceeds the next logical control to achieve more accurate and stable system.

-FAQ


Q1.Tell me the standard of package?
A. For the small capacity, it uses carton, but for big capacity, we should use strong wooden case for protection.

Q2.Do you accept OEM/ODM?
A. It is totally not a problem. We can prepare relative documents to the foreign affairs office or other offices to apply for this certificate.

Q3.Would you accept to use our logo?
A.Yes,it is available. But we have MOQ for that.For details, pls talk to the customer service.

Q4.Where is your market?
A. Our products are popular in Russia, Indonesia, Philippines, Italy, America, Pakistan and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefit from our cooperation.

Q5.What kind of certificate do you have?
A.We can provide CE,ROHS,FCC,IEC62133,MSDS,UN38.3 as customer requires.But for details and fee, we need to talk in detail with the sale manager.
