Self reconfigurable, adaptable power electronics building block (A-PEBB)
摘要
說(shuō)明書
Internally, this existing PEBB 1000 LRU hardware configuration also leverages matured and available 1.2 kV or 1.7 kV rated SiC MOSFET and/or 1.2 kV or 1.7 kV IGBT devices for switching. Known legacy PEBB 1000 LRUs are commonly rated at 85 kW to 125 kW in power, and provide voltages ranging from 680V-to-1 kV DC or from 480V AC to 707V AC. For one megawatt (1 MW) or less power applications, and for a 12 kV or below power applications, a common or unified hardware power converter is typically architected using twelve (12) PEBB 1000 LRUs with paralleled or cascaded connections on each side of the PEBB 1000 LRU (depending on application's voltage requirements). Typically, legacy maritime power converters (involving pulse loads, energy storage, and energy magazines) employ twelve PEBB 1000 LRUs in the converter, and are rated for conversion of 1 kV DC to 450V AC; 1 kV DC to 4160V AC; 1 kV DC to 6 kV DC; or 1 kV DC to 12 kV DC PEBB.
Fixed-Ship-Mission Power-Converter Design Limitations
In legacy art, power converters for ships and other limited space applications are typically designed within the framework of a specific, fixed power architecture designated for use on a manned ship with an established, relatively well-defined mission or range of missions, with a suitable-but-fixed set of power sources and power requirements. For example, a first ship ‘A’ may be a military vessel (such as a destroyer or cruiser), a second ship ‘B’ may be a research vessel, and a third ship ‘C’ may be a cargo or transport vessel.
