The world's leading manufacturer of motor and drive technology, presents the new series of MVW3000 variable speed drives with nominal voltage from 2.3kV to 8kV and nominal power from 280 kW to 2,400 kW. This family of devices incorporates multilevel technology and H cascade bridges (CHB). The multilevel topology is based on the serial connection of three to ten low voltage IGBT (690V) power modules, depending on the output voltage. In this way, voltage levels in the medium voltage range can be achieved using, in a cost-effective manner, proven standard low voltage components (diodes, IGBTs, and plastic film capacitors). As a special feature, the MVW3000 is supplied as a complete system integrated into a distribution cabinet, including medium voltage disconnect switch, fuses, multilevel power transformer, and variable speed module.
“The current-voltage and power range is only the first stage in the evolution of the product. Higher voltages and powers are available if requested, ”says Johannes Schwenger, Product Manager for Low and Medium Voltage Drive Systems in Europe for WEG. no additional medium voltage switchgear. This variable speed drive system is distinguished by its extraordinary input and output parameters and excellent levels of energy efficiency and availability.
