The Danfoss VLT 12-Pulse Drive offers reduced harmonics for demanding industry applications above 250 kW.
The VLT 12-Pulse Drive 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 needs.
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.
