Power levels in the traction inverters today go above 200kW. Requirements for the increase in the power density brings together the requirements for the increase in the motor speed. The speeds of a motor go up to 20000rpm. Since the efficiency has a direct effect on the driving range, automotive companies are doing the evaluation running some of the driving cycles (CLTC, WLTP). This document presents the efficiency during the CLTC together with the key parts which help in achieving the efficiency target.
