Galvanically Isolated 200 kW DC-DC Converter

A galvanically isolated DC-DC converter transfers power between two DC systems while electrically isolating the input and output sides. This improves safety, protects sensitive equipment, reduces ground loop issues, and enables integration between systems operating at different voltage levels.

DCKraft™ provides full galvanic isolation between input and output, preventing circulating currents and protecting connected systems from ground faults or disturbances on the DC bus. This isolation ensures operational safety, signal integrity, and long-term reliability in industrial, renewable, and marine environments where system separation is essential.

The converter is based on Silicon Carbide (SiC) power semiconductors, enabling efficiencies above 99% with very low switching and conduction losses. Optimized magnetics, high-frequency operation, and advanced cooling design minimize thermal stress, delivering stable and repeatable performance across varying load conditions.

A bidirectional DC-DC converter enables controlled power flow in both directions between DC sources, energy storage systems, and loads. This allows the same converter to support both charging and discharging operation, reducing system complexity and improving overall energy efficiency. In applications such as battery energy storage systems (BESS), fuel cells, hydrogen infrastructure, marine electrification, and DC microgrids, bidirectional converters enable regenerative energy recovery, peak shaving, DC-bus stabilization, and flexible energy management. DCKraft combines bidirectional operation with galvanic isolation and high-efficiency Dual Active Bridge technology for safe and reliable operation in demanding high-power environments.

Bidirectional power flow allows batteries and other storage systems to both receive and deliver energy using the same converter. This is essential for applications such as battery charging, grid support, renewable energy integration, and energy balancing in DC microgrids.

Yes. DCKraft is based on modular 200 kW converter units that can be combined into multi-megawatt systems, providing flexible scalability for high-power industrial and renewable energy applications.

DCKraft™ is designed for DC-based energy and industrial systems such as fuel cells, battery storage, hydrogen production, DC grids, and on-shore power. Its bidirectional design and adaptable voltage range make it suitable for both energy conversion and stabilization tasks across renewable and transport sectors.

Dual Active Bridge technology provides high efficiency, soft switching, galvanic isolation, and bidirectional power transfer. It is particularly suitable for high-power DC-DC conversion applications requiring compact design, scalability, and reliable operation.

Yes. Each installation can be customized for voltage range, current capability, communication protocol, and enclosure type. KraftPowercon’s engineering team provides factory-tested, DNV- and CE-certified solutions optimized for marine, industrial, or stationary use — ensuring conformity and consistent quality worldwide.

By combining high efficiency, galvanic isolation, and modular scalability, DCKraft™ enables safe, low-loss power conversion between distributed generation, storage, and loads. It plays a key role in building efficient DC infrastructures for renewable energy, green hydrogen, and electric mobility — supporting the global shift toward electrification with lower system losses and higher reliability.
