Wärtsilä Active Front End Drive - LV

This variable speed drive solution is delivered with an active rectifier front end. This allows for energy flow in both directions, thus eliminating the need for transformers and braking resistors.

The Wärtsilä Active Rectifier provides Direct Current Control and network filter, giving small ripple currents and very low harmonic distortion well below the requirements of international standards. It is specially designed for lifetime operation in a maritime environment, and the world’s most compact low voltage (690V) variable speed drive.

The drive features excellent performance for the control of propulsion motors, pump applications, compressors, mooring and winches, and drilling operations. The drive is water cooled and can be directly connected to the ship’s cooling water system. Other important features are the redundant design and interchangeable power modules, which provide an easy and efficient service concept.
