However, the new auto industry is doing very well, thank you. Kelley Blue Book tells us (via Cox Auto) that sales of pure EVs… Read more »

Silicon carbide is becoming the material of choice for EV power electronics

Silicon carbide is a hot topic in the power electronics field these days. As a recent article in the New York Times explains, SiC is a wide-bandgap (WBG) material that designers are increasingly choosing to make power electronics devices more efficient. WBG advantages The WBG classification has profound implications for device behavior and performance. This… Read more »
