WEG, a global leader in motor and drive technology, has launched the new MVW3000 medium voltage variable speed drive (VSD) series. Designed for demanding industrial applications, the drives support nominal voltages from 2.3 kV to 8 kV and power ratings from 280 kW to 2,400 kW, delivering reliable and energy-efficient performance.
The MVW3000 incorporates advanced multilevel IGBT technology with Cascaded H-Bridge (CHB) topology. This design connects three to ten low-voltage (690 V) IGBT power modules in series, enabling medium voltage output while using proven and cost-effective standard components such as diodes and plastic film capacitors.
As a fully integrated solution, the MVW3000 is supplied within a compact distribution cabinet. The system includes a medium voltage disconnector switch, fuses, a multilevel supply transformer, and the variable speed drive module, eliminating the need for additional medium voltage switchgear and simplifying installation.
According to Johannes Schwenger, Product Manager for Low and Medium Voltage Drive Systems in Europe at WEG, the current voltage and power range represents only the first stage of the product’s evolution, with higher ratings available upon request. He emphasized that the MVW3000 offers excellent input and output performance, high energy efficiency, easy maintenance, compact design, and outstanding operational availability.
With its robust design and superior efficiency, the WEG MVW3000 medium voltage drive is ideal for applications such as pumps, fans, compressors, conveyors, mining, oil and gas, water treatment, and power generation, making it a versatile solution for modern industrial environments.
