Comparing data sheets for SiC switches can be difficult. SiC MOSFETs can appear to be at an advantage with a lower temperature coefficient of on-resistance, but this is an indicator of higher underlying losses and overall lack of efficiency compared with UnitedSiC FETs.

The increase in demand for high efficiency, high power density and system simplicity makes silicon carbide (SiC) FETs an appealing choice for power engineers due to their fast switching speed, low RDS(on) and high voltage rating.

Wide band-gap semiconductors have already shown their advantages in power switching applications but have not yet made inroads into the very high voltage/high power area where IGBTs are dominant. However, ‘Supercascodes’ using SiC FETs are set to challenge the status quo.

Electric vehicles seem to be the realization of decades of futuristic ambitions, but actually, in 1900 they outnumbered gas-powered vehicles by nearly two to one. Today, EVs are finally taking their place again as serious contenders in the vehicle market, enabled by advances in motors, batteries, chargers and the electronics that interconnect them.

Mechanical switches and actuators are becoming a thing of the past in modern vehicle cockpits. Under the hood, mechanical switching and isolation of high current and voltage connections can now also be replaced by latest SiC semiconductors.

EV uptake is set to increase but ‘range anxiety’ and charge times are still barriers to general acceptance. Wide bandgap semiconductors are enablers for more efficient motor drives and faster charging and new SiC FETs are best performers.

When you think about it, we live in an atypical world. We often hear or use the word ‘typical’ in a way that is synonymous with ‘average’, but in statistical terms, there is guarantee of average occurring even once, so forget about it being typical.

New generations of semiconductor switch technology appear faster and faster and SiC is no exception. In its infancy still, next generations of this wide band-gap technology promise further improvements in efficiency, size and cost in many application areas.
