30 Years and Going Strong - by Alan Mantooth

The IEEE Power Electronics Society (PELS) will be celebrating its 30th anniversary in 2018. We will commemorate this milestone with events to be held at both the IEEE Applied Power Electronics Conference and Exposition and IEEE Energy Conversion Congress and Exposition this year as well as with a special compendium of IEEE Power Electronics Magazine. I will stop short of giving away those exciting details, but we are busy working on it. Stay tuned! Read More...


Upcoming Events

Upcoming Webinar: Flux Modulation Machines

The presentation will discuss major SiC power device application areas and touch on foundry models, cost reduction strategies, and path to commercialization. The advantages of SiC over other power electronic materials will be outlined, and SiC devices developed for power electronic applications will be introduced. Emphasis will be placed on SiC MOSFETs, which are currently being inserted in the majority of SiC based power electronic systems. Aspects of device fabrication will be summarized, stressing processes that do not carry over from the mature Si manufacturing world and are thus specific to SiC. Finally, the presentation will highlight common SiC Edge Termination techniques, which allow power devices to reach their full high-voltage potential. Read More...

Differential Power: A Fundamental Limit of Power Conversion

In this talk, the main novelty is the “VA interpretation” of power conversion, that enables the calculation of novel continuous power models for 2-port and n-port converters. This methodology also enables the synthesis of specific power topologies to operate in this fundamental limit of power processing. 
Key applications are “Power balancing” between stacked sources (PV cells), loads (data processing cores) or batteries. “Partial power” configurations may also be assessed with the “differential power” approach. More relevant is the case of energy buffered converters, as those required in single-phase inverters connected to domestic batteries/PV panels or those required in AC adaptors and chargers with Power Factor Correction.
Three-phase rectifiers and inverters may be also be synthesized to operate in the fundamental limit of power conversion. The methodology is illustrated for the “Little Box Challenge” (Google and IEEE-PELS) specification. The differential power is calculated, and compared with the “indirect” power processed by the main alternative architectures. Finally, an inverter is synthesized to operate in this fundamental limit.
