Abstract
This paper compares a matrix converter (MC) and a DC-voltage link
converter with an active front end for a 7.5 kW, 460 V induction motor
drive. Part count, semiconductor losses, input filter design, and
protection aspects are discussed. It is shown that the matrix
converter's semiconductor losses are smaller only at full load operation
for the same silicon area in both converters. A 33% reduction of the
device current rating of the MC is possible, resulting in comparable
thermal device stress. The overall passive component count and rating is
only slightly better for the MC
