DC-link chokes (2 lines)
DESCRIPTION
Power Noise Reduction – save energy costs.
The DC-link choke is used for smoothing the DC link current and to reduce mains harmonics in voltage source inverters.
The typical combinations of rectifiers and capacitors strains the supply network significantly. For functional reasons, the current consumption of the power supply or the inverter is not sinusoidal but pulsed at the moment of maximum voltage. DC-link reactors reduce the harmonics and relieve the supply network similar to the line reactors. In addition, the DC-link reactor attenuates charging current peak surges of the DC-link capacitors. By using a DC-link reactor the supply network is less burdened with harmonic reactive power.
Improvement of the efficiency of a converter (Power Factor Correction). Starting currents and current peak are attenuated up to 70%. Line reactors help to comply with international power quality standards IEEE 519 or EN 61000-3-2.
ADVANTAGES
