Concepts such as the Integrated Power System (IFS) and the DC Zonal Electric Distribution System (DC ZEDS) have motivated the study of power inverter control and paralleling strategies by the U.S. Navy. For example, in DC ZEDS a Ship Service Inverter Module (SSIM) converts DC power into AC power for use within a zone. For reasons of redundancy and logistics, multiple paralleled inverter submodules are used to implement the SSIM. ...
The Navy's interest in implementing a DC Zonal Electric Distribution System (DC ZEDS) in the next generation of surface combatant has motivated considerable research work into dc-dc converters. The switching frequency of a hard-switched dc-dc converter is limited by the maximum admissible switching losses allowed by the switch, heat sink, and cooling process. Also, hard- switched converters contribute significant Electromagnetic Interference (EMI) concerns for ...
The Navy is actively engaged in developing Power Electronic Building Blocks (PEBBs) for its initiatives into DC Zonal Electric Distribution (DC ZEDS) . DC ZEDS is a key element of the Integrated Power System (IPS) effort which seeks to modify the current surface combatant so that both ship service and ship propulsion electrical loads are powered from a common set of prime movers. Presently, the current generation ...
