Adaptive onshore power conversion systems for maritime applications

The global shift towards sustainable transportation has led to increased efforts to decarbonize sectors beyond private vehicles, including the maritime and industrial transport systems. As ports and shipping activities become more electrified, new challenges arise to ensure power delivery and charging efficiency along with infrastructure design. Electrification of vessels, ranging from small ferries to large cargo ships, demands fast, high-power charging systems that are compatible with a wide spectrum of battery technologies and voltage levels. Minimizing emissions in port areas has become critical for improving urban air quality and meeting international climate goals. Beyond ships themselves, ports rely heavily on land-based equipment such as trucks, automated guided vehicles, forklifts, and reach stackers. These machines, traditionally diesel-powered, contribute significantly to local emissions and noise pollution. As port authorities move toward full electrification of the port ecosystem, there is an urgent need for charging infrastructure that can efficiently support a wide range of electric powertrains both floating and terrestrial. Motivated by these challenges, this thesis addresses the design of high-efficiency power converter systems for onshore charging applications.
