Reliable Power Electronics Systems
Abstract:
Power electronic interfaces are essential for regulating power flow between different voltage levels and frequencies. Several AC/DC and DC/DC converters have been developed to perform this flexible control functionality between various sources and loads. A deeper understanding of the reliability of such converter topologies is important because converter applications such as smart EV charging, wireless power transfer, grid ancillary services, battery energy management systems, e-mobility, and intermittent renewable energy sources (wind, PV) can stress the internal power electronic components in very different ways.
Thereby, lifetime estimation considering mission profiles with adequate redundancy, modularity, and reconfigurability is relevant so that the designed power electronic components comply with the operation life requirements of the larger fault-tolerant system.
