Line Reactors and AC Drives - Rockwell Automation
literature.rockwellautomation.comGenerally drives less than 10 hp do not have a dc link reactor. And in most cases that’s not a problem since any harmonic current distortion would be small when compared to the total load of the facility. If many small drives are required for a process, an input reactor is a valid method in reducing harmonics. In

Technical Guide No. 102 - ABB
library.e.abb.comdrives, as are most AFDs available today. Figure 1 illustrates the basic principles of an ABB PWM drive. The rectifier converts input line power, which has a nom-inally fixed voltage and frequency, to fixed voltage DC power. The fixed voltage DC power is then filtered to reduce the ripple voltage resulting from the rectifi-cation of the AC line.
