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
