Power electronics devices are widely used in the rail transportation equipment, new energy vehicles, industrial control, net-work reconstruction, and many other areas. However, in the middle and high-end field more than90% of the power semiconductordevices still rely on imports. Power semiconductor industry of Hunan province has a good foundation, so we should seize the devel-opment opportunity, adhere to the industrial chain thinking, accelerate the layout of third-generation technology products, expand theapplication demonstration of key industries, focus on cultivating the industrial ecosystem, and build a competitive power semicon-ductor innovation and industrialization base in China. Based on the basic characteristics of Hunan power semiconductor industry de-velopment, this paper identifies the development weaknesses, and puts forward countermeasures and suggestions from the aspects oftop-level design, leading enterprises, innovation platform, demonstration and application, and domestic alternatives.
