Miniaturized Power Management that Disappears & Merges with the Environment
Abstract:
The need for an efficient power management solution has never been more critical across virtually all electronic devices and systems from low power to high power, smartphones to data centers, battery-powered components to renewable-energy-powered grids, and from stationary systems to aircraft. Particularly for ultra-low power systems such as untethered sensors and IoT systems, the key challenge is to maintain high delivery efficiency while satisfying increasingly demanding input/output requirements, space constraints, reliability, and cost, simultaneously. Aiming to address this grand and increasingly difficult challenge, the speaker will present multiple approaches centered arou...

Architectures, Topologies and Control for High-Frequency Power Electronics
Просмотров 248Год назад
Abstract: Power converters designed for higher frequency operation than conventional designs can be smaller and lighter. However, to gain these benefits and maintain high reliability the converters also need to be more efficient, as smaller converters offer less surface area for heat removal. The development of efficient, small and light weight power converters can benefit from converter archit...

Common Mode EMI Analysis and Mitigation Methods in Three-Phase Inverters
Просмотров 1,6 тыс.Год назад
Speaker: by Prof. Giovanna Oriti Abstract: The common mode (CM) voltage generated by a switching power converter yields unwanted currents to circulate in the ground paths, tripping ground faults relays, accelerating motor bearing aging, and producing electromagnetic interference (EMI). Typical differential mode (DM) models of power converters do not account for CM paths and currents, so models ...

Abstract: Transformer equivalent circuits based on modeling magnetic coupling or mutual inductance describe important aspects of transformer behavior such as leakage inductance and cross regulation. Transformer equivalent circuits based on adding L-R networks typically focus on winding losses predicted by Dowell's method, but they often don't model coupling effects, and they typically don't wor...

July 25, 2019 Abstract: See how we can take a resonant (LLC) kernel of a certain wattage at a certain frequency and scale it to any power level and any frequency, using scaling laws, hitherto virtually hidden in plain sight. See how that helps also understand current wireless power techniques, which as will be revealed, are simply LLC topologies in disguise, provided of course they are executed...

The Trials & Tribulations of Evaluating GaN and SiC Switching Devices Activities
Hi mam. This is a very helpful video for me. Actually, I am doing research in EMI reduction, particularly DC-DC converters in EVs. Could you please help me to measure CM and DM noise of the converter in Matlab simulink. I need some reference circuits or video.. It would be very helpful for my research.
😣 *Promo SM*
Good program. Very hard to understand the speaking. Need to take your audio from a close microphone, maybe split the one the speaker is talking into. That will also get rid of the echo. OR shotgun microphone pointed at the speaker. I am surprised how well Google transcription works though.
Sorry but i can hear him clearly
@@Tuong11a You are probably younger than me and better selectivity in your hearing. I heard a lot of room reverberation because the mic is not close to his head and so picks that up to well. Listen to the audio of a professional TV broadcast and you will notice that they try hard to eliminate the room echo to make it easier for old folks like me and others. Reduces listening fatigue for many too.
@@k7iq hi K7iq. I didn’t mean that. I just find out this professor born in same country as me. Then he came to USA. That explains why i can hear him more clear.
@@Tuong11a Okeee DOkee. Yes that would help a lot I am sure ! Thank you. I just like to help people get a better more understandable sound if I like their video or channel. He is one I would like to do well.
great work bro keep creating
I sadly learned he passed away in Feb 2021. I enjoyed his book and have learned a lot from him.
Would like to find out what kind of Lithium batteries were on those fatal flights ! Not what manufacturer, but what genre of Li batts
Yes, the grid can be used as a giant battery but utilities no longer want to share their big battery 😀
Prof. Jungwon Choi is awesome presenter.
RIP SM

Indeed enlightening session! Only part I didn't like was that remark at @33:47 , "Graduate students are cheap labors!"
Can you send me ZVS and ZCS occur in LLC
Sir any design tool is there.
Sir how to limit the igbt output current in llc converter how to tune tank ckt

That was a good hearing about dq. Does anyone have the PDF of this presentation, please?
Explain about continued miniaturization in nanoelectronics
Thanks guys! You will find a version with embedded slides and some animations, to make this MUCH MUCH clearer: ruclips.net/video/U9t6X5nivv8/видео.html
Nah...even worst, just you wanted to have more likes in your site
I have read this author's textbooks. They are really good.
Jump to 11:30 to skip the preamble.
Talk proper starts at about 10 minutes in, check ewh.ieee.org/r6/scv/pels/archives.html for slides and other info.
Actual talk starts about 13 minutes in.
Thanks for saving my time
Apologies for the poor audio - equipment failure :-(
