How multilevel converters and SiC can improve sustainability
Modular multilevel converters (MMCs) are an advanced form of a voltage source converter. They are emerging as the preferred choice in medium- and high-voltage green energy applications like high-voltage DC (HVDC) transmission systems, medium voltage motor drives including electric vehicles (EVs), wind and solar renewable energy systems, battery energy storage systems (BESS), and EV chargers […]
Rare earths and EVs – it’s not about batteries
Rare earths play an important part in the sustainability of electric vehicles (EVs). While there are sustainability challenges related to EV batteries, rare earths are not used in lithium-ion batteries. They are necessary for the magnets that form the main propulsion motors. The batteries mostly rely on lithium and cobalt (not rare earths), while the […]
EV basics: Comparing innovative battery chemistries
While lithium-ion battery chemistry dominates the current electric vehicle market, scientists are working to develop innovative battery chemistries that address the known challenges the existing chemistry presents. By Adam Kimmel for Mouser Electronics Sales of electric vehicles (EVs) continue to outpace the overall automotive segment, with EV market shares of 5.2% in Q1 and 5.6% […]
