Audited Supplier Working principle:
The workingprinciple of the IGY APF series active powerfilter is to detect the load current inreal time,separate theharmonic currents one by one based on the specified harmonic current detection algorithm,and generate controlsignals according to the set filtering percentage to drive theIGBT output and the load harmonic current amplitude,compensation currents with the same value and oppositephase achieve the purpose of harmonic cancellation.
Features:
1.Use DSP+CPLD all digital control core,three-level topologytechnology,advanced harmonicdetection algorithm andPWM control strategy to achieveaccuratecompensation of harmoniccurrent
2.Adopt modular design,which facilitates parallel connection of multiple modules,takes up
3.The structural designof independent air ducts and independent warehouses ensures thestable operation of the equipment.
4.It can filter harmonics in a wide rangeof harmonics,from 2 to 50 harmonics,and solve theproblem of three-phase unbalance at the same time
5.The harmonic filtering rate is high.If the capacity allows,the harmonic current filtering ratecan be as high as 95%.
6.Set 100%current limitingoutput to ensurelong-term stable operationof theequipment.
