Thanks to their fast switching and reduced losses, SiC wide-bandgap devices help designers achieve efficient, integrated motor drives, enabling them to reduce size and get closer to the motor to lower costs and improve reliability.
The most important development in power electronics in recent years is the rise of so-called wide-bandgap (WBG) materials, namely silicon carbide (SiC) and gallium nitride (GaN). Read more

The blame game is in full swing in the aftermath of Texas’ severe ice storm. Between February 14th and the 19th, Texas experienced record-setting low temperatures for a sustained period. It is estimated that over 3 million customers lost electricity, not just for hours, but for days. During the course of that week, many people also were without water. Read more
