UofT and Sendyne to offer progressive power supply type for cell phone equipment

A joint collaboration involving the University of Toronto and Sendyne Corp., New york, has yielded a new circuit that enables a smaller sized, lighter battery and electrical power subsystem for tablet PCs together with other portable devices.


The volume occupied by the power supply circuit continues to be a limiting aspect for miniaturization of your electronics in mobile gadgets. Existing power supply patterns occupy anyplace in between 20% and 80% in the volume of this kind of products, based upon the application. A substantial portion of this volume is determined by the size of inductors and capacitors used in such power supply circuits.


For being presented on the IEEE Utilized Energy Electronics Conference (APEC) and Exhibition in Fort Well worth TX on Thursday, March 20th, the circuit addresses these troubles. This topology consumes significantly less power than would generally be needed to keep secure dc bus voltage output from the battery subsystem in portable devices, and achieves a 9X reduction in size and cost of your output capacitor. Since the trend in new gadget layout is usually to use dual cell batteries for optimization of energy delivery and cell life, the new architecture also supplies for economical, lossless balancing of your batteries in dual cell methods. Experimental success obtained from an 8-12V, 20W, 250KHz prototype demonstrate a peak efficiency of 93.4%.


The APEC presentation is entitled, !§Assisting Converter Based mostly Integrated Battery Management Process for Minimal Energy Applications.!‥ Main the venture group is Professor Aleksandar Prodic, from your Electrical and Computer Engineering (ECE) Department in the University of Toronto. He is the founder in the Laboratory for Energy Management and Integrated SMPS, exactly where the development is happening. Dr. Prodic, a recipient of a number of IEEE awards and distinctions, is surely an skilled in electrical power process design.
