Abstract:The use of Silicon carbide (SiC) devices represents an improvement in terms of size, weight and efficiency of power converters. However, SiC-based solutions present high dv/dt and di/dt on the switching events, increasing the common-mode noise injected into the grid. To reduce the common-mode noise, three-phase inverters with a DC-link referenced output filter are widely considered in photovoltaic (PV) inverters connected to the grid. However, if the filter is DC-link referenced the inductor ripple is larger, … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
