Abstract

The traction inverter is one of the crucial parts of every electrical vehicle. The trend to go to 800V battery system and SiC devices with high switching frequency helped significantly in increasing inverter efficiency. To have a highly efficient system, both hardware and software need to have high performance, from the advanced technology ICs, layout, and precise sensors for the feedback signals, to the control algorithms and fast control loops that control the switches. Increased inverter efficiency means lower losses, but one of the main questions is what effect increased efficiency has on the electrical vehicle. In this paper, we show the systems requirements followed by high-power test results of 300kW, 800V traction inverter (TIDM-02014) and four key factors that are influenced by the inverter efficiency.
