heal.abstract	MVDC Architecture on Ships - Summary This diploma thesis explores the development and application of Medium Voltage Direct Current (MVDC) systems in shipboard power networks, positioning MVDC as a key enabler in the future of marine electrification. It compares MVDC systems with traditional MVAC (Medium Voltage Alternating Current) setups, focusing on architecture, performance, integration of renewable energy, and regulatory issues. Key points: Efficiency & Integration: MVDC improves energy efficiency, reduces space and weight, and integrates well with batteries, fuel cells, and renewables. Design & Control: Discusses shipboard MVDC layouts (radial, ring, zonal), converter types, and advanced control strategies. Challenges: Focuses on technical difficulties in protection and stability due to the lack of natural current zero-crossing in DC systems. Case Studies: Highlights projects like ZEUS (hybrid fuel-cell ship), Angle-DC (UK grid link), and US Navy applications. Future Outlook: Examines the potential of wide-bandgap semiconductors (SiC/GaN) and high-temperature superconducting (HTS) cables.	el
