UofT and Sendyne to provide revolutionary power supply style for mobile phone devices

A joint collaboration among the University of Toronto and Sendyne Corp., Ny, has yielded a fresh circuit that permits a smaller, lighter battery and power subsystem for tablet PCs and various moveable products.

The volume occupied from the power supply circuit is a limiting aspect for miniaturization from the electronics in mobile devices. Existing power supply designs occupy anyplace concerning 20% and 80% from the volume of such products, determined by the application. A significant portion of this volume is determined by the size of inductors and capacitors used in such power supply circuits.


To get presented with the IEEE Applied Electrical power Electronics Conference (APEC) and Exhibition in Fort Really worth TX on Thursday, March 20th, the circuit addresses these challenges. This topology consumes significantly less energy than would commonly be expected to retain steady dc bus voltage output on the battery subsystem in moveable gadgets, and achieves a 9X reduction in size and expense with the output capacitor. As the trend in new gadget style should be to use dual cell batteries for optimization of power delivery and cell daily life, the new architecture also presents for economical, lossless balancing of the batteries in dual cell programs. Experimental results obtained from an 8-12V, 20W, 250KHz prototype show a peak efficiency of 93.4%.


The APEC presentation is entitled, !§Assisting Converter Primarily based Integrated Battery Management Program for Low Power Applications.!‥ Main the undertaking team is Professor Aleksandar Prodic, from the Electrical and Computer Engineering (ECE) Department with the University of Toronto. He is the founder with the Laboratory for Power Management and Integrated SMPS, wherever the advancement is taking place. Dr. Prodic, a recipient of various IEEE awards and distinctions, is surely an skilled in energy process style and design.
