Averaged Value Analysis of l S-Pulsc Rectifiers for Aerospace Applications

چکیده مقاله

Power electronic based power systems are increasingly
being used in applications such as aircraft, spacecraft, hybridelectric
and electric vehicles and many more. In these multi
converter power electronic systems, different converters are
integrated together to form a complex and comprehensively
interconnected system. The replacement of hydraulic and
pneumatic systems in aircraft with electrical systems is known
as the "More Electric Aircraft (MEA)". This concept is being
used increasingly in the aerospace industry and is resulting
in the growing and widespread use of electrical power and
power electronic components and systems. More electric components
and systems are expected to enhance reliability, faulttolerance,
power density and performance of aircraft systems.
For example, many of the main pumps associated with fuel and
lubrication are currently coupled directly to the engine. In the
MEA approach these are likely to be driven by variable speed
electrical drives with associated power electronic converters.
Also, the use of new converter topologies with advanced power
components as the power switches are predicted to increase
system efficiency.
