چکیده
This study presents different technologies and topologies of medium-voltage (MV) drives available on the market. The paper describes the advantages and disadvantages of each configuration and the impact in the quality of energy in the mains and motor sides when using them is also analyzed. Technical requirements and practical considerations for end users and system designers are identified for a proper selection in this field. In addition, results of experimental tests are presented using a Neutral Point Clamped High Voltage IGBTs (NPC-HV-IGBTs) on a Voltage Source Inverter (VSI) operating in three different control modes: Volts/Hertz, Closed Loop Vector Sensorless and Closed Loop Vector with encoder. These results are shown with the intention of analyzing the performance of this topology.
