Abstract

This paper calculates and compares the efficiency and loss distribution in three most popular state-of-the-art types of medium voltage drive systems; current source drive with active front-end rectifier, current source drive with 18-pulse thyristor rectifier, and three-level voltage source drive with 12-pulse/24-pulse diode rectifier. Based on the proposed simple and accurate method of calculating switching losses, snubber and filter losses, three-level voltage source drive system has been found to produce the highest efficiency of 98.77% under the rated load of 1.6 MW
