Medium voltage industrial variable speed drives
Monday, 18 May, 2009
This tech paper 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 analysed. 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 on a Voltage Source Inverter operating in three different control modes: Volts/Hertz, Closed Loop Vector Sensorless and Closed Loop Vector with encoder.
