Welcome to this installment of EE Classroom on Grid Infrastructure


As the surging energy demands of today stress out an already stressed 70+ year old power grid never designed for the increasing longer distance power transfers let alone the charging of EVs and HEVs, more sophisticated power electronics and processors have become the best hope for grid stabilization. But with those specialized chips comes the challenges of not only staying current with the technology but designing for the future.


Here you will find resources to assist you in that journey and provide resources to aid in your designs. These include frequently asked questions around EV charging with a look at the power design differences between internal combustion engines and EVs, as well as the hardware and software considerations required. Also included are basic tutorials around other grid-infrastructure-related technologies such as power line carrier communications, and photovoltaic inverters — the heart of a PV system and just one of the realistic paths available to transforming a grid of the past into at least the beginnings of a more sustainable and evolving grid of the future.
