Power systems are experiencing a significant transformation with the implementation of emerging technologies to face 21st-century challenges such as decarbonization, digitization, and decentralization. The penetration of renewable energy is increasing worldwide, and initiatives such as distributed energy resource (DER)-based microgrids play a vital role in generating electrical power with fewer environmental impacts.

All-Electric Vehicles (EVs), BATTERY-powered EVs (BEVs), and plug-in hybrid EVs (PHEVS) are gaining market share and increasing in popularity with the buying public because the battery range (longer) and cost (lower) have reached sweet spots, the charging infrastructure is more robust, and concern with global climate change is high. In 2013, only 100,000 EVs were sold in the United States, but by 2022, approximately 800,000 have been purchased. A similar growth is seen in EV supply equipment (EVSE), i.e., EV charging stations, with 19,742 documented EV charging station locations in the United States in 2013 to 50,054 documented EV charging station locations, with approximately 130,000 ports, by the end of 2022.

As the electric drive finds its way progressively into important industry sectors like mobility, transportation, agriculture, production, and supporting services, it becomes increasingly important to have individually optimized technical solutions for the manifold applications. Therefore, a high number of engineers with interdisciplinary competencies will be needed soon to comply with the demand of the worldwide markets. A key component for an often-used variant of the electric drivetrain is the full-bridge inverter, which is subject to a wide spectrum of different requirements. In 2021, the University of Denver (DU), started a cooperation with the University of Applied Sciences Augsburg (UASA) to develop a full-bridge inverter for an autonomous, electrical Formula Student race car, using four permanent magnet synchronous machines as an all-wheel drive. To improve the performance of the race car, the inverter must be lightweight, package optimized, electromagnetic compatibility compliant, safe, and reliable when it distributes a maximum of 80 kW instantaneous power from the battery at a voltage between 420 V and 600 V individually to the four wheels. This article documents the inverter development process using silicon carbide MOSFET power modules, with the goal of using future results in the race car and the knowledge transfer for the education of engineering students. This transatlantic partnership between DU and UASA also serves as a success story for intercontinental collaborative development based on modern communication and decentralized development techniques.

This article is about electric shore power connections in port for vessels in regular service. The main purpose is to reduce emissions from vessels while in port, and for some vessels, to include charging onboard batteries. This article does not cover the needs of vessels under repair, laid-up vessels, and permanently moored vessels.

Modern ports are expected to play a key role in the transportation chain, being transformed into smart grids and smart energy hubs where electric energy needs predominate. Cold ironing (CI), also known as onshore power supply (OPS) or alternate marine power, is indeed one the most energy-demanding applications. The power demand of a berthed ship depends on its characteristics and may vary from hundreds of kW, for container ships, to tens of MW, in the case of cruise ships.
