The Navy is currently facing an unprecedented challenge to develop new ship designs under compressed schedules that incorporate emerging technologies for high power energy conversion in order to enable smaller ship designs with a high degree of electrification. Also, in order to enable the Navy’s vision for more precise electric weapons, next generation ships will rely upon MVDC and an Integrated Power and Energy System (IPES). The emergence of wide band gap power semiconductor multi-chip modules, such as SiC MOSFETs, are a significant factor that must be considered in enabling higher voltage application of power electronics and potentially more power dense equipment. The most viable IPES architecture along with the optimal level of MVDC voltage and the right topologies for power distribution and conversion equipment must be identified. A unique “virtual prototyping” methodology is proposed for determining Pareto-optimal designs for power conversion cabinets based on Power Electronic Building Blocks (PEBBs). Once power distribution and conversion cabinets with their respective functional allocations and selected optimization criteria is fully defined and characterized, multi-objective optimizations can be performed at the ship level in order to determine the most viable approaches for a given ship design.

Rob Cuzner is an Assistant Professor at University of Wisconsin-Milwaukee. He was previously a Staff Systems Engineer at DRS Power and Control Technologies where he worked for 21 years on the development of power conversion equipment for Navy Shipboard Integrated Power Systems, electric propulsion and shipboard compatible variable speed drives. His research focuses on two main areas: (1.) Development of power electronic topologies and systems that are power dense with high input power quality and electromagnetic compatibility in constrained space environment; and (2.) Fault protection methods for microgrids and dc distribution systems to enable resilient, reliable and reduced energy usage power delivery. Dr. Cuzner received his Ph.D. and M.S. degrees from the University of Wisconsin-Madison and B.S. degree from Brigham Young University.
