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 around physical, architectural, and functional integration of advanced power management units with the systems that allow them to efficiently and essentially disappear/merge with the environment. Design examples and results from the iPower3Es group at UCSD and state-of-the-arts will also be covered as demonstration.

Architectures, Topologies and Control for High-Frequency Power Electronics
Переглядів 245Рік тому
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...

    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.

    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.

      @@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.
