beautiful work! leaving aside the thermal resistance and power calculations, that we are familiar with, the bigger picture in this video, i do not remember me finding it anywhere else. i'd say this video is an awareness video, so to speak. we, because we are many, thank you!
I am mostly working on circuit part of traction inverter, to me Dc link and igbt and thermal always very interesting also difficult . Thank you very much professor.
Thank you for making this video. It would be interesting to compare these low capacitance cooled polypropylene to a C0G ceramic based design with paralleled high temp, high voltage packages on a copper substrate. For the capacitance used in the example, i.e. 0.17uF, it seems like the C0G design with ~53 parallel 0.0033uF 2kV C0G capacitors would be a lot less expensive, lower volume, with better heat dissipation and a longer expected lifetime. Would like to find out if I'm missing something here because I use this on a daily basis...
Indeed, NPO can be an alternative but due to 20 minutes limits that I have set for he video I did not put it in. My experience is that for high current the PP has the upper hand, not to mention the complexity of a large CC matrix. Be aware that the current data of ceramic capacitors is given for a single unit mounted on a one square inch PCB covered with copper.
Very interesting video as always! I'll take this opportunity to ask you a question. Are you planning on releasing further videos on LLC? I'm currently designing an LLC with adjustable output voltage, and I know that LLC is not the best suitable topology for wide output voltage range (in my case 2V-30V), however I would really like to implement LLC for its softswitching capability. All the "design guides" and videos I've seen are using fixed output voltage. I can imagine there will be a lot to consider with wide output voltage range. If you'd ever do a video on this topic, I would very much appreciate it! Thanks.
@@sambenyaakov sure sir I will go through once again...as today is Thanks giving day ..I would like to thank you for all your videos only because of your videos I was able to switch to the power electronics domain and working in one of the leading Aerospace company.for me your videos are a one stop solution and everyday before starting my day at the workplace first I watch your video then I start the work .. once again many thanks for the job you did so far and looking for same in the upcoming years... please take care and stay healthy 🙏🙏

👍🙏 several videos on my TH-cam channel are related to DC capacitors. E.g. th-cam.com/video/ovzeCSx7yH4/w-d-xo.html

pretty interesting, didnt even know these kind of devices existed before

Indeed, LLC is not that good for wide output range. Some designs use an additional stage for that.
Hi sir when is the next video coming up... eagerly waiting
Baking
Did you see it?
@@sambenyaakov yes sir the time when you uploaded at that time only
@@biswajit681 I have deleted the first one that had an audio problem and uploaded a corrected version
