UnitedSiC announces SiC FETs with RDS(on) of less than 10 mohms
Range and horsepower may get the headlines, but to powertrain designers, drain-source resistance, also known as RDS(on), is a sexy spec. Those in the know are excited over the news that UnitedSiC, a New Jersey-based manufacturer of silicon carbide (SiC) power semiconductors, is introducing four new SiC field-effect transistors (FETs) that boast RDS(on) levels of… Read more »
Why did Porsche go to the trouble of designing an 800 V Taycan EV?
How higher-voltage battery packs enable faster charging ecosystems Porsche took on a considerable engineering challenge when it decided to design an 800 V EV system for the Taycan, because nearly every other hybrid and EV in the world operates at 400 V or less. There simply was not a wide range of high-voltage off-the-shelf parts… Read more »
