Low harmonic drive systems with Active Filter Solutions

Active Filter solutions

The use of power electronics on board of vessels and other electrical installations causes undesired harmonic distortion.

Our Active Filter Solution (AFS) is capable of reducing the harmonic distortions in a highly effective manner, by means of injection of current in counter phase to the disturbance in order to cancel the harmonic distortion.

The negative effects of harmonic distortion are:

  • Extra heating of generators, transformers and e-motors      
  • Nuisance tripping
  • Breakdown of sensitive equipment
  • Flicker

For new build

A clean power supply, small footprint, and interesting investment rates are key topics when designing the electrical installations of new vessels: Introducing the Active Filter Solutions (AFS) of Bakker Sliedrecht.

Our AFS are a great way of creating low harmonic drive systems with a small footprint and without the use of transformers. They save valuable space thanks to their compact size and low weight. Moreover, AFS are highly flexible as they can actively target predefined harmonics  up to 50th harmonic. They also allow integration in the drive system or elsewhere in the installation. AFS require a low investment compared to 12-pulse or active front end drive systems.


  • Cost effective
  • Compact
  • Light weight
  • Highly flexible

For retrofit and conversion

Are you experiencing issues such as unexplained equipment breakdown and overheating? Or do you want to save on operational costs? Bakker Sliedrecht can analyze and improve the power quality on board your vessel.

Bakker Sliedrecht can measure and analyze the power quality of your installation in case you are experiencing harmonic distortion issues. In case of poor power quality, our AFS for existing electrical installations can solve the issue. AFS require little space and can be installed within or nearby you electrical installation. AFS are easy to install, require a low investment, and solve harmonic distortion issues effectively.


  • Plug and play
  • Compact
  • Highly effective
  • Problem soving


AFS are currently being installed on the Bibby Wavemaster 1. Click here for more information.
