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 [...]

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 [...]
