Abstract To succeed
in the transition from mechanical to electrical
propulsion in submarines and smaller combatant
ships the navy needs power electronics equipment
that is smaller, lighter and more efficient than
current technology. The described high efficiency
quiet electric drive (HEQED) combines step-mode
switching (SMS) and pulse-width modulation (PWM)
to provide a highly efficient converter system
with the capability to control noise signature.
The Motor drive is considered as "high efficiency
quiet motor drive" because it eliminates
approximately 80% of switching losses in power
semiconductors as compared to conventional drive
systems. The rectifier building blocks, operating
as synchronous rectifiers, produce lower voltage
distortion by enabling more effective suppression
of harmonic feedback to the AC source. The
electric drive is able to compensate for
imperfections in the drive motor and is
programmable to compensate for changes in the
motor from time and wear.
