Frede BlaabjergMoving Forward With the Baton

 by Frede Blaabjerg

From 1985 to 1987, I was a master’s student at Aalborg University, Denmark, working with power electronics and field vector-oriented control of electrical drives. The switching frequency was 20 kHz to make the drive silent, and we were using a combination of MOSFETs and bipolar transistors to obtain such speed in the power stage. Simultaneously, by sampling around 5 kHz, the processor was pushed to the limit by using the Assembler software. At that time, all of the technology we utilized was the state of the art.  Read More...

Upcoming Webinar: Online Prognostic Condition Monitoring for Wind Turbines Using Current Signals

Thur, April 25, 2019 11:00 AM EDT

 Presenter: Wei Qiao, University of Nebraska-Lincoln 

Wei QiaoAbstract- This webinar will present the pioneering work conducted by the Power and Energy System Laboratory at the University of Nebraska-Lincoln, Lincoln, NE, USA on low-cost, online, prognostic condition monitoring (PCM) for wind turbines and their mechanical and electrical subassemblies, such as gearbox, bearing, blade, drivetrain, and generator. The PCM methods primarily use current signals acquired from generator terminals or in the power electronic converter control system to online diagnose and prognose the faults and predict the RUL of the wind turbines in all operating conditions. In addition to current signals, the PCM can also be used to include vibration signals in wind turbines to provide additional PCM capability and improved diagnosis and prognosis accuracy.

PELS/IAS Joint webinar: Powering the next decade by reviewing the past


Stephanie ButlerPresenter: Dr. Stephanie Watts Butler
Technology Innovation Architect, Texas Instruments
The IEEE Energy Conversion Congress and Exposition (ECCE) recently celebrated its tenth anniversary – a decade that coincided with an unprecedented shift in technology for power generation, delivery, and conversion. This shift, coupled with the advent of smart phones and IOT, has enabled an explosive growth in electronification in industrial, consumer, and automotive markets. According to IC Insights, power management ICs ship in greater quantity than any other type of IC device. The resulting broad application corresponds with an impressive expansion in the features and capabilities of power semiconductors to address the vast scope of end equipment needs. This presentation will examine the changes in power management semiconductors over the past decade. Integration, system in package, voltage levels, and process technologies will be discussed. How different features are necessary for different markets and applications will be considered. The webinar will conclude with an examination of this year’s Applied Power Electronics Conference (APEC), demonstrating the continued expansion of semiconductor capabilities and applications.
