On shore power connections

A DC/DC converter is the core power conversion link between the onshore energy source and a vessel’s internal DC grid. KraftPowercon’s DCKraft™ isolated converter provides the required galvanic isolation between land and ship, ensuring safe, fault-free, and compliant power transfer — even under demanding port-side conditions. It replaces bulky 50/60 Hz transformers with a compact, high-efficiency isolation stage that reduces footprint and simplifies installation.

When connecting a vessel directly to the port grid, land-to-ship galvanic isolation is mandatory to prevent circulating currents, corrosion, and electrical hazards. The DCKraft™ converter integrates this isolation internally, delivering the same safety function as an 800 kVA transformer while reducing space and weight dramatically.

By replacing multiple conversion stages with a single high-efficiency DC/DC interface, DCKraft™ minimizes conversion losses and stabilizes power flow between the port grid, battery buffers, and vessels. Its modular topology enables up to 10 MW scalable output, ensuring smooth load transitions and improved grid compatibility even when multiple vessels connect simultaneously.
