Abstract

An exemplary breaker-less, medium voltage DC distribution system capable of meeting the demanding operational and performance requirements of, for example, a Navy combatant, is disclosed. Survivability is maximized in the disclosed architecture by providing multiple, individually-controlled power feeds from each “islanded” turbine generator. The system takes advantage of the rapid response of power electronics for fault protection without the penalty of having to shut down major segments of the electrical system to isolate a fault. The use of a multiphase generator configuration with multiple rectifiers (PCM4s) provides for system redundancy and provides better fault tolerance, since the greater the number of rectifier modules used, the less impact a rectifier or bus fault will have on system performance.
