Power engineers in another design camp, working to ensure their fast chargers can speedily top up EVs, are also aware of the cost of electricity and the environmental impact of its generation. Engineers targeting any application area are joined in their concerns over efficiency, power density, and cost. And, even if they have yet to design with it, they are aware that the solution may lie in Silicon Carbide (SiC) technology. An essential part of UPS and charger systems is the active front end (AFE), to explore improvements in size and power density, power losses and efficiency, and bill of materials (BOM) costs. It aims to turn that general awareness of SiC benefits into a clearer understanding, clearing a path through an entrenched less-efficient technology toward greater SiC-based design experience. This article addresses these concerns and, by doing a side-by-side comparison, demonstrates that Silicon Carbide is by far the better choice over Silicon (Si)- based devices for high power applications.
