challenges similar to that of the automotive
industry in terms of improving emissions,
fuel economy, and also cost. The increasing
use of electrical and electronic features to
improve vehicle performance, fuel economy, passenger comfort, safety, and convenience has resulted in the growth of
electrical loads in automobiles. The potential electrical loads
include the engine cooling fan, engine coolant pump, active
suspension, electric assist power steering, electrically heated
catalytic converter, electric power take-off, electric brake-bywire, heated windscreen, telematics, and navigation. The U.S.
government's current rules for the Corporate Average Fuel
Economy (CAFÉ) program mandates an average of approximately 29 mi/gal, with a gradual increase to 35.5 mi/gal by
2016 (39 mi/gal for cars and 30 mi/gal for trucks). This will
increase to 54.5 mi/gal starting from the 2025 model year. The
electric, hybrid/plug-in hybrid vehicles, and fuel cell vehicles
are considered the solutions to meet the above challenges.

The electrical power being used by both civil and military
aircraft is also growing. Electrically powered environmental
control systems, electrical actuators, and electric de-icing are
some examples of the aircraft systems under consideration.
Modern military aircraft are equipped with powerful radars,
sensors, weapon systems, and sophisticated cockpit displays
that require large amounts of electricity to operate. Commercial airliners must also provide power for environmental systems, including galley equipment, cockpit displays,
communication systems, weather radar, and in-flight entertainment systems. The intent is to move as many aircraft
loads as possible to electrical power, resulting in simpler aircraft systems. This leads to the potential for lower fuel consumption, reduced emissions, and reduced maintenance, and
possibly lowers cost.
The Advisory Council for Aeronautics Research in Europe
has set several goals to be achieved by 2020 for air transportation. These include a 50% reduction of CO2 emissions
through a drastic reduction of fuel consumption; an 80%
reduction of NOX emissions; a 50% reduction of external
noise; and a green design, manufacturing, maintenance, and
disposal product life cycle. Hence, there is a move toward
