Starting from the importance of power density in electric vehicle traction inverter, this article reviews the current international technical standards based on the 2025 blueprint goals set by the US Drive Association. By analyzing the key components of the traction inverter, this article takes volume ratio and hardware and software technical indicators as the optimization direction for improving power density, and combines the development direction of international trends in recent years to bring out the current research and design status of the Intelligent Mobility Technology Division in Industrial Technology Research Institute. By comparing and analyzing the current international benchmark products as a reference, we hope to surpass the power density blueprint target set by US Drive in the United States, thereby driving the development of domestic traction inverter technology.
