UofT and Sendyne to supply gradual power supply form for cell phone products

A joint collaboration involving the University of Toronto and Sendyne Corp., Ny, has yielded a whole new circuit that permits a smaller, lighter battery and power subsystem for tablet PCs and also other moveable devices.


The volume occupied from the power supply circuit continues to be a limiting factor for miniaturization of your electronics in mobile units. Latest power supply types occupy anywhere among 20% and 80% of your volume of such devices, based upon the application. A significant portion of this volume is determined by the size of inductors and capacitors used in this kind of power supply circuits.


To get presented in the IEEE Utilized Power Electronics Conference (APEC) and Exhibition in Fort Really worth TX on Thursday, March 20th, the circuit addresses these problems. This topology consumes much less power than would usually be expected to preserve stable dc bus voltage output on the battery subsystem in transportable products, and achieves a 9X reduction in size and cost of your output capacitor. Since the trend in new gadget layout is always to make use of dual cell batteries for optimization of energy delivery and cell existence, the new architecture also offers for low-cost, lossless balancing of your batteries in dual cell systems. Experimental results obtained from an 8-12V, 20W, 250KHz prototype demonstrate a peak efficiency of 93.4%.


The APEC presentation is entitled, !§Assisting Converter Based Integrated Battery Management Program for Minimal Power Applications.!‥ Main the project group is Professor Aleksandar Prodic, from your Electrical and Computer system Engineering (ECE) Department of the University of Toronto. He's the founder in the Laboratory for Electrical power Management and Integrated SMPS, the place the improvement is taking place. Dr. Prodic, a recipient of a number of IEEE awards and distinctions, is surely an skilled in electrical power method layout.
