A common problem when installing drives on an existing vessel is the increase in harmonics on the ship’s grid. This can be especially disruptive because the grid is often not sized for such changes in electrical loads. Additionally, there is often a space constraint, making it challenging to fit conventional low harmonic drives, particularly large AFE drives.
While the common solution to this issue has been to use AFE drives or multi-pulse transformers for large loads, with ADF, the filter is decoupled from the drives. This makes it possible to be placed anywhere and greatly simplifies installation, providing flexibility in decision-making and space-utilization.
