Electric and hybrid vehicles continue to demand a share of the automotive market. This movement has been mainly enabled by recent technological improvements in the realm of electric motors, power electronics, and energy storage. While many electric vehicles are on the market, they are not as cost competitive as the conventional vehicles, and this is needed for large-scale market penetration. In order...
With the advancement of technology on wide bandgap materials such as silicon-carbide (SiC), there are now better choices of SiC power devices available than ever before. It is widely known that SiC-based switching devices provide significant performance improvements on many aspects including lower power dissipation, higher operating temperatures, and faster switching frequencies compared to conventional...
