Recommendation
Current position:Home > Passive Harmonic Filter > Passive Harmonic Filter
Circuitry application:
At the input side of 6 pulse rectifying installation(frequency converter、DC speed-regulator、the integrated rectifier cabinet at electric vehicle charging stations), it can help to ameliorate distortion rate of current&content of harmonic, improve the power factor of equipment.
Test effect:
The following outcomes are comparisons between 15KW inverters adding and without the passive harmonic filter:
