WEG Manufactures & Supplies World’s Most Energy Efficient & Relible Mv Frequency Inverter For Usa Pumping Application.

“In a single stroke we have doubled the output of our MV inverter range to 8000- HP, producing an outstanding product range that delivers 99% efficiency and 22- year MTBF, making them the most highly efficient and reliable medium voltage inverter in the world.” said Marek Lukaszczyk, WEG’s European Marketing Manager.

“It’s important to note that 99% efficiency is an average 1% more efficiency than that delivered by any other medium voltage inverter on the market - and this can mean an economy of up to US$ 50,000 per year for this particular user”, said Mr. Lukaszczyk.

The market-leading performance of the MVW-01 is due to the WEG MV drive having just two-layer control, rather than the 3 or 5 layers of conventional MV drives, and its integration of state-of-the-art and highly reliable components, such as HV-IGBTs. This unique combination of an optimised architecture with a reduced number of highly proven components results in outstanding improvements in efficiency and reliability.

With the development of the new MVW-01 to 8000HP, WEG has become the first and only South American company capable of producing and testing equipment with this power range. The tests, essential to assure the equipment will support the real load during operation, have never been performed before, due to their complexity, risk and high cost. “We have made substantial investments in the construction of a new laboratory, and in expanding the dynamometer in our testing area, making us the only company in SA able to offer this kind of service”, said Marek Lukaszczyk.

The MVW-01 drives are Voltage Source Inverters (VSI) employing the latest multi-processor control architecture. They integrate a 32-bit high-performance processor (64-bits bus) with floating point capability to provide high-performance control of MV motors such as WEG’s “H” Line range.

The MVW-01 inverter technology also integrates state-of-the-art and highly reliable components, such as HV-IGBTs, which are used on high speed trains in Europe. This technology allows the inverter to be used in the most demanding applications, such as the mining, cement, shipping, iron metallurgy and petrochemical industries.
