Title
: Towards Perfect Power Quality: Concepts, Root Causes, and Solutions

Abstract: Electric power quality problems, specifically harmonics, can be traced back to as early as the invention of the electric power delivery system in the 1890s.  Back then, the power system encountered harmonic resonance, which caused the motor to experience overvoltage and to overheat.  In this talk, I will show that all power quality problems, though each may have different outward forms, share the same underlying principles: undesirable currents interact with the system impedance, giving rise to voltage problems. Fundamental and broad-based solutions will be proposed to achieve ‘perfect’ power quality.  However, like potholes on the roads, power quality problems are always with us.  Practical solutions will be presented and will include something old, something new, something futuristic, and something in between.

Speaker: Surya Santoso, Professor of Electrical and Computer Engineering at the Cockrell School of Engineering, The University of Texas at Austin




Biography: SURYA SANTOSO is a Professor of Electrical and Computer Engineering at the Cockrell School of Engineering, The University of Texas at Austin.  He earned his B.S in Electrical Engineering from Satya Wacana Christian University, Salatiga, Indonesia in 1992 and M.S.E and Ph.D. in Electrical and Computer Engineering from The University of Texas at Austin in 1994 and 1996.  He was a postdoctoral fellow under the auspices of Electric Power Research Institute in 1997.  He was Senior Power Systems and Consulting Engineer with Electrotek Concepts in Knoxville, TN from 1997 until 2003.  He joined the faculty of The University of Texas at Austin in 2003.  His research interests lie in the broad area of transmission and distribution systems, modeling and simulation, and automated root-cause analysis of power quality disturbances.  In the past 20 years, he and his students have published over 40 journal and 100 conference papers.  His publications have been cited over 8,500 times.  In addition, he has the privilege of having supervised over 15 doctoral and 30 M.S students who have become professors, researchers, engineers, entrepreneurs, and medical doctors in the U.S and abroad.

He co-authored Electrical Power Systems Quality, now in its third edition, with Roger C. Dugan, Mark F. McGranaghan, and H. Wayne Beaty, and he is also the sole author of a college textbook, Fundamental of Electric Power Quality.  Along with H. Wayne Beaty, he is an editor of the Handbook of Electric Power Calculations, now in its fourth edition.  He taught IEEE Plain Talk on Power Quality in IEEE PES General Meetings between 2010 and 2014.  He currently serves as IEEE PES Distinguished Lecturer in the broad areas of electric power quality and wind power systems since 2013, editor of IEEE Transactions on Power Systems since 2014, Technical Committee Program Chair and Secretary of the IEEE PES Transmission and Distribution Committee between 2015 and 2017, and 2017 and 2019, respectively.  He is an IEEE Fellow.

 

October 24: Fast, Small, Efficient: The Series Capacitor Buck Converter

Abstract:
This presentation will introduce the series capacitor buck dc-dc converter developed at Texas Instruments. Point-of-load voltage regulators typically use buck converters operating in the hundreds of kHz range. Their size is dominated by passive components, especially inductors. The series capacitor buck topology overcomes conventional high frequency challenges and enables efficient operation in the multi-MHz range. The topology is a unique hybrid of a switched capacitor circuit and a buck converter. This presentation will overview the operation, control, and implementation of a 2-5 MHz series capacitor buck converter and include sample results with comparisons to state-of-the-art buck converters.

Speaker: Pradeep Shenoy, Systems Engineer at Texas Instruments

Biography: Pradeep Shenoy is a Systems Engineer in the buck switching regulators business unit at Texas Instruments. His area of expertise is high frequency, small size voltage regulators. He received the B.S. degree in electrical engineering from the Illinois Institute of Technology, Chicago, and the M.S. and Ph.D. degrees in electrical engineering from the University of Illinois, Urbana-Champaign. He received the Illinois International Graduate Achievement Award in 2010 and the Jack Kilby Award for Innovation in 2015. He serves as the North America Regions Chair of the IEEE Power Electronics Society.

Analog Newsletter

The electronic IEEE Central Texas Section newsletter, The Analog, provides news of many of the other IEEE activities in the Austin and San Antonio areas. If you are an IEEE Central Texas Section member, your subscription is provided automatically to the email address in your IEEE profile. If you are not a member, you may subscribe following the procedures provided at the The Analog Webpage.

Be advised that there is not a lot of traffic on this list intentionally. The list manager tries to keep it below 3 emails a month - The Analog, the mid-month reminder, and maybe an emergency announcement, but we prefer 2 emails a month .
