Extended base speed range by using a current-source-inverter-fed IPMSM for automotive application

This paper proposes a power train structure including a CSI with an integrated buck-converter to feed an IPMSM for automotive application. An optimized operation strategy to 1) extend the base speed range and 2) maximize the system efficiency is introduced. Simulated system performance and efficiency are presented and compared to the conventional VSI-based power train.
