Abstract: Silicon carbide (SiC) power semiconductor modules exhibit comprehensive performance advantages over traditional Si modules, such as higher voltage endurance, lower switching losses, and higher operating junction temperatures. They hold vast potential in high-temperature, high-power applications like multi-electric aircraft and electric vehicles. However, the development of these applications poses increasingly demanding technical challenges for SiC power modules, including tolerance to higher environmental temperatures, reduced size and weight, and enhanced reliability. Addressing these challenges, this report explores advanced packaging and integration technologies for SiC power modules, including high-temperature SiC power module packaging integration, low-inductance SiC power module packaging, and rapid short-circuit protection for SiC power modules.
