Using an active front-end to reduce AC VSD harmonics

An article from ABB looks at how harmonics caused by AC drives can be mitigated using passive filters or active front-end drives. Passive filters cost less and can be effective under some circumstances; the challenge lies in establishing just what those circumstances are. If the required conditions for a passive filter are difficult to meet, […]
