![]() This search is informed by semiconductor material and process improvement (silicon-based thyristor, GTO, MOSFET, IGBT, IGCT), and also by converter topologies that use multiple cells or switches. Often several technical solutions achieve a project's goals, especially when dealing with high power converters.Power semiconductor manufacturers are in search of the perfect switch - one with high voltage and current capability, as well as low losses. From device to converterīuilding a power converter has always been a compromise between available power semiconductor switches, converter topology and system requirements. The emergence of complex electrical architectures in marine applications will increase the need for power converters with high reliability and simple maintenance requirements. Converter design is still restricted to specialists nevertheless, the advent of stacks is a step toward simpler system construction. This gives a good overview on a system level, but hides a lot of technical problems that converter designers have to handle. Complex power electronics systems are represented as the interconnection of conversion blocks, as in AC/DC, DC/AC, DC/DC and AC/AC. Power electronic is a key technology in optimizing energy management, providing the conversion needed to operate motors, generators, battery storage and shore supply. The use of power stacks in marine electric system construction can answer the demand for complex electrical architectures.Īs in many other fields, marine applications have to cope with environmental regulations.
