ENGINEERING TOMORROW VLT® 12-pulse drive Robust and cost effective harmonic solution for the higher power range. The Danfoss VLT® 12-pulse drive offers reduced harmonics for demanding industry applications above 250 kW. The VLT® 12-pulse is a high efficiency variable frequency converter which is built with the same modular design as the popular 6-pulse VLT® drives. It is offered with similar drive options and accessories and can be configured according to customer need. Together with the needed 30°-phase shifting transformer the solution provides durability and reliability at a low cost. Under ideal grid conditions the solution eliminates the 5th, 7th, 17th and 19th harmonics and results in a THiD of around 12% at full load. The needed transformer makes this solution ideal for applications where stepping down from medium voltage is required or where isolation from the grid is needed. The Danfoss VLT® 12-pulse drive provides harmonic reduction without adding capacitive or inductive components which often require network analysis to avoid potential system resonance problems.
