Smartenance DC-DC On-Board Power Converters
IEEE Transactions on Circuits and Systems II: Express Briefs, 2023—Traditional marine power grids, using diesel motors/generators, pollute the atmosphere with their CO2 emissions and adverse particles. Nowadays, green energy supplies like solar systems and fuel cells play significant roles in the electrification of marine propulsion plants. In general, marine power systems with green energy units are often considered

Power density maximization of DC-DC converter
2011 1st International Conference on Electrical Energy Systems, 2011This paper proposes a method which consists of a phase shift converter with a current doubler rectifier on the output side, the phase shift converter operating at frequency as high as 20–25kHz (depending on the requirement of the application). Ferrite core transformer is used instead of conventional one, which being bulky leads to very large amount of ...

IGBT based high power DC-DC converters
10th IET International Conference on AC and DC Power Transmission (ACDC 2012), 2012In this paper, a type of high power DC-DC converter based on IGBT switches is proposed. Basically, the converter consists of two bidirectional IGBT bridges linked by a pair of energy storage capacitors. It is capable of MW power transfer and can achieve very high voltage ratios.
