HVDC (High Voltage Direct Current) technology is particularly suitable for the transmission of high-power energy over long distances. However, some technical/technological problems have to be addressed/managed when passing from HVAC to HVDC due among others to the fact that the electric field distribution in gas insulated systems (GIS) operating under DC stress is very different from AC conditions.

In the future, Medium Frequency Transformers (MFT with a frequency range 5 kHz to 100 kHz) will be major components in DC-DC converter applications, for both Medium Voltage Direct Current (MVDC) and High Voltage Direct Current (HVDC) networks. Importantly, the corresponding power losses should be accurately calculated in order to reach performance targets (very high efficiency).

SuperGrid Institute has succeeded in the preliminary tests on their first DC-DC power converter in September 2015. The power converter nominal power is 100 kW with an input voltage of 1 kVdc and an output voltage of 500 Vdc. The converter topology is a Dual Active Bridge with silicon carbide transistors and a medium frequency transformer.
