Silicon vs Silicon Carbide Transistors - Workbench Wednesdays

Silicon Carbide transistors lower the cost of power converters in high-power applications of 25 kilowatts and higher. But how are Silicon and Silicon Carbide different? On Workbench Wednesdays, learn from James the differences between the two transistor types and some considerations for using them in a design. Also, see some simulation tools available from onsemi.
Discuss the episode, find the resources, and ask James questions on the element14 Community! bit.ly/3KGg2wm

I wish every video in my feed was as useful as this video

[@HillsWorkbench]

A lot of information presented quickly but clearly.

[@didierbalocco1611]

Very good video and very well structured. Good Job. Thank for promoting onsemi great Elite Power Simulator with Model Generator.

This is great news for the electronics world! I'm excited! I remember when Mosfets arrived. Gonna be nice to see cell phone sized power inverters and audio amps pushing more than their thermal dissipation capabilities.

[@Musliperanto]

I wish my videos as brilliant as this video.

[@jokervt000]

Could you tell me the simulation / schematic tool you are using?

How abot SiC vs. GaN?

[@bald_engineer]

They tend to be found in different places in the power converter market. High-voltage/power tends to favor SiC while Lower-voltage tends to favor GaN. SiC has lower on-resistance compared to GaN, but GaN can operate at higher frequency than SiC. So for high power converters (10 kW and much higher) SiC is more favored for efficiency. But for low-power converters (think laptop/USB-C chargers) the higher-frequency capability of GaN means much smaller devices.

@@bald_engineerExcellent summary, thanks!

[@duyhai1869]

Great news for industry

[@haveehere6651]

nice! Can you do a video showing the topology differences for rectifier applications in Hydrogen ?

[@metallicsigma]

why you made gate between two source terminals?

[@bald_engineer]

It is a cross section ...

[@MrNathanstenzel]

Is this new or old information?

[@MrNathanstenzel]

Ah. It looks like there are recent advancements in gallium nitride and silicon carbide based chips.
