ABB.
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 braking ability,
possible [...]
Below you will find technical data of medium voltage drives manufactured by ABB.

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 the [...]
