Abstract
Efficiency and recuperation capabilities of
modern electrical drives have become very important features
within variable speed drive applications. Regenerative
electrical drives are therefore usually equipped with cost
extensive pulsed active front end topologies for the
recuperation mode. Contrarily, the much cheaper
fundamental frequency switched front end is used. It has no
electrolytic capacitor with its limiting effect on the operating
temperature and lifetime. Additionally to the converter
topology, the used squirrel cage induction or alternatively the
permanent magnet based machine shows different advantages
with respect to the efficiency-torque characteristic within
variable speed drives.
