Passive Harmonic Mitigation Solutions for Variable Speed Drives: Benchmarking LRC Filters Versus 18-pulse Rectifiers
ثبت نشده
چکیده
Every electrical circuit is a potential source of electrical interference, particularly when switching reactive loads. Most electrical interference is low level and has no noticeable effect on other branches of electrical equipment. Variable speed drives, however, are highly non-linear loads; input rectifiers produce a high level of harmonics that may affect the performance of other devices connected to the same electrical supply. Active or passive filters can be used to improve the power quality in the branch.

متن کاملA Novel 36-pulse rectifier with low kVA rate to reduce harmonic input current distortion
The increase in the number of pulses in multipulse rectifiers leads to a reduction in harmonic current distortion. But this increase in the number of pulses leads to an increase in kVA, cost, and complexity of the multi-pulse rectifiers. As a result, in industrial applications, 12-pulse rectifiers are mainly used due to their lightweight, simple transformers, and low kVA rate, and low cost. The...
