Perspectives of high-voltage SiC-semiconductors in high power conversion systems for wind and photovoltaic sources

SiC devices become increasingly interesting at higher blocking voltages against their Si-based counterparts in order to reduce losses and obtain cost savings by means of higher switching frequency and low component count. The possible gains along with an overview of related constraints valid at high power levels will be discussed in this publication, taking as example power conversion nstages for photovoltaic and wind energy systems.
