DC/DC Converter for 400V DC Grid System
2022 IEEE International Conference on Environment and Electrical Engineering and 2022 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2022In the photovoltaic (PV) to grid structure, DC-DC converters are essential to increase the low input voltage gener-ated by renewable energy sources. The Single Ended Primary Inductance DC-DC Converter (SEPIC) allows for an output voltage higher or lower than that of the input.

A Bidirectional Isolated Multiport DC-DC Converter for DC grid
2021 IEEE Southern Power Electronics Conference (SPEC), 2021Multiport DC/DC converters (MPC) is becoming a promising configuration to integrate DC grids with different voltage levels. This paper presents a neutral-point clamped (NPC) converter-based MPC (NMPC), which is developed to interconnect medium voltage DC (MVDC) grid and low voltage DC (LVDC) grid. The circuit topology and operation principle of NMPC is

LCL DC/DC Converter for DC Grids
IEEE Transactions on Power Delivery, 2013This paper proposes an LCL dc-dc converter concept which is capable of achieving very high stepping ratios with megawatt-level power transfers. The converter can find potential application in connecting high-power dc sources to high-voltage dc transmission including future dc transmission networks.

DC/DC converter for offshore dc collection grid
International Conference on Renewable Power Generation (RPG 2015), 2015Offshore wind represents a significant clean energy resource. Current offshore wind farm designs use a conventional AC collection network in which the wind-turbine AC output voltage is stepped up to a medium-voltage suitable for wide area connection. A DC offshore collection grid offers an attractive alternative to an AC architecture as it avoids the ...

DC-DC converter for HVDC grid application
2017 National Power Electronics Conference (NPEC), 2017There is an increasing interest in voltage source converter (VSC) based HVDC grids. The development of DC grids is likely to take place in phased manner with several voltage levels similar to that of the AC grids. These different high voltage DC levels will have to be interconnected with each other which will require DC-DC transformers.
