Full SiC power module optimized for electric/hybrid traction motorsports apps
Marelli has launched the first power module for motorsports electric and hybrid traction applications completely developed in the company’s Corbetta facility, fully based on Silicon Carbide (SiC) technology and using a new direct cooling solution. This leading-edge system will be the core building block for even more efficient, compact, and lighter inverters. The new module, […]
Under the hood of PV inverters
One of the advantages of photovoltaic (PV) energy is that it is inherently modular. Unlike many other energy sources, it allows the implementation of small-, medium- and large-scale generation systems, ranging from portable and rooftop systems to large multi-megawatt PV farms. System requirements, performance specifications, regulations, and even the economics behind the different system sizes, […]
