Wärtsilä Passive Rectifier Drive - LV

The Wärtsilä Passive Rectifier Drive is well suited for operation with either a Wärtsilä LLC system or a standard transformer solution.

This variable speed drive solution is delivered with a diode rectifier in 12, 18 and 24 pulse configurations.

Especially designed for extended operating life in a maritime environment it is the world’s most compact low voltage (690V) variable speed drive, and features excellent 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, all of which make service easy and efficient.

    • Siem Pearl
      The Siem Pearl became operational in August 2009. The Wärtsilä clean design hybrid solution consists of a combined diesel-electric and diesel-mechanical system. This means the ship can switch between different modes to achieve continuous and optimal efficiency. Compared to conventional diesel-mechanical vessels, dynamic positioning operation offers fuel savings of up to 50%.
