00:38 - What does SiC bring to power electronics systems, that IGBT, MOSFET and Super Junction MOSFET don't?
01:43 - What is the difference between Carbide (SiC) and Gallium Nitride (GaN) power devices?
02:33 - What are the applications where SiC should be considered the default choice and why?
03:23 - What types of SiC devices are available today?
04:04 - Which industries are moving towards SiC, is it just where higher power is needed?
04:46 - What are cost levels of SiC compared to Silicon only, is there are premium and if so why?
06:21 - What are the key operating differences?
07:47 - What about power conversion in consumer electronics which is dominated by silicon, will SiC emerge
08:30 - Is it true that due to packaging materials used, that SiC is only practical for low-frequency circuits? At higher frequencies Capacitance and Inductance become an issue? If so what frequency ranges are they suited to?
10:15 - Loved ROHM's SiC article on DesignSpark. Is SiC considered to be an alien material then?!
11:07 - Electrically powered cars are big news, are you working in partnership with any Automotive manufacturers in developing the technology and moving away from the reliance on fossil fuels?
12:42 - Can SiC MOSFETS be designed within circuits as a replacement for Silicon, or do you need to consider wider operating characteristics when including SiC?
14:04 - What is the ideal gate resistance value when connecting SiC MOSFETS in parallel?
14:49 - Why is there undershoot/overshoot of the gate signal during SiC device drive?
15:57 - How can I mitigate the undershoot and overshoot of the gate signal when using SiC products?
16:26 - What happens to the gate voltage drive in SiC MOSFETS and modules when deviating from the recommended values?
18:05 - Is a negative bias required for the gate drive voltage in SiC MOSFETS and modules?
