Difference in the design process of LCL filters for grid connected VSI when using SiC/GaN instead of Si semiconductors

Although the design of LCL filters has been discussed extensively in recent years, the different requirements for the design process when using SiC/GaN semiconductors instead of classical Si semiconductors have not been presented in detail. Due to the higher switching frequency, new EMI limits in lower frequency range and other influencing factors, there are some differences, which must be taken into account in the design process. This enables a more resource-saving use of materials as well as a faster development time.
