Due to its high thermal conductivity, high insulation, high dielectric strength, and low dielectric loss, aluminum nitride ceramics are widely used in large-scale integrated circuit chip carriers, silicon-controlled rectifiers, high-speed switching modules, audio and microwave power amplifiers, optoelectronic integrated circuit functional modules, IGBT modules, and more. Power modules encapsulated with aluminum nitride materials have already been applied in high-speed rail, new energy vehicles, rail transit, solar power generation, wind power generation, electric energy storage, smart grids, and other fields.

The core technologies of new energy vehicles include power batteries, electric motors, and control systems. In the control systems, a large number of IGBTs are required, such as in motor control systems, vehicle air conditioning control systems, and charging systems. IGBTs play a crucial role in new energy vehicles and are one of the core components in such vehicles.

IGBT devices are widely required in smart grids and energy internet, with main application areas including flexible AC transmission, flexible DC transmission, smart transmission, and new energy integration.
