ABB has recently introduced a new medium voltage drive – ACS 2000. It is IGBT based five-level diode-clamped* voltage source inverter. Main product features according to the manufacturer documentation are: AFE 5-level IGBT rectifier with transformerless design** (direct-to-line connection is possible), two-winding input transformer is an alternative, full load/speed input power factor correction and regenarative [...]

ACS 1000 Topology Voltage Source Inverter – Three-level Neutral Point Clamped Input section Diode rectifier – 12 or 24 pulses – no regenerative braking ability Input voltage 2300V, 3300V, 4160V Efficiency >98% at rated load excluding isolation transformer Input power quality 24 [...]
There are few manufacturers of medium voltage drives. Each of them offers different drive topologies with specified advantages and drawbacks. In successively published posts I will provide brief product specification and links to available documentation. At this point I will not compare specific solutions. In the following posts I will present offer of companies with [...]
