The results are highest efficiency, higher switching frequencies, less heat dissipation, and space savings – benefits that, in turn, also reduce the overall system cost. We identified this potential almost 30 years ago and established a team of experts in 1992 to develop SiC diodes and transistors for high-power industrial applications.
