Abstract:

The 20 kHz power systems, currently being considered for the Space Station and advanced
spacecraft, can produce harmonic resonances which, in some cases, may cause component
damage and electromagnetic interference. Controlled suppression of these harmonic
resonance frequencies is the purpose of this project which will investigate methods
of filtering the harmonic frequencies by using either passive or active filtering
at the load and/or source interface. Phase I will provide the means for filter design
and set the stage for Phase II. This Phase would develop detailed models of typical
spacecraft power systems in order to establish a simulated test bed for designing
and evaluating autonomous systems before committing to hardware. A second aspect
of Phase II would be development and verification of reduced order models of the
power system components for use in a digital simulation of the overall system. 

Potential Commercial Application:

Potential Commercial Applications:  This could have application in any group, federal
or commercial, interested in the design and operation of a 20 kHz power system for
aircraft of any type.
