High Efficiency at Low Currents: A Necessity For Notebooks 
Oct 17, 2007
Power-supply designers routinely tackle new dc-dc converter design tasks with the goal of achieving the highest efficiency possible. Clearly, this task is a very complex one. Once the topology has been selected based on the specifics of the application, a designer must go through a very rigorous process of component selection. ...

The Technician Can Be a Key Contributor to Modern Power Research 
Sep 25, 2007
Today's technicians are fully capable of prototyping a design. They can layout the pc board using modern software tools, do the assembly, perform electrical and thermal testing, and generate a lab report with their findings. This great leap in capabilities allows design engineers to concentrate on multiple project activities....

Mathematical Spreadsheets and Simulators: Both Belong in Your Toolbox 
Aug 29, 2007
I have discovered that using mathematical spreadsheet software like Maple gives me a totally different experience in understanding how different individual parameters affect the final performance of the circuit....

PCB Layout: The Final Weapon In The Power Designers'Arsenal 
May 17, 2007
Should the completion of the circuit design be the end of the road for power designers? After all, once the circuit is verified they have met their design goals, it is time to move on to the next project—right? I say no. ...

Digital Power: Still Looking For A Killer Application 
Apr 18, 2007
In 2005, I presented a conference paper in which I argued that the power-supply industry would only switch from analog PWM controllers to fully digital controllers if a killer application were found. Here it is two years later and the killer app has yet to be identified — but why?...

High-Density Power Modules: The Way of the Future 
Mar 23, 2007
The field of power conversion is going through a transformation akin to that produced by the first bipolar transistors; only today, it's a combination of semiconductor and packaging technology that's driving the field to high-density integration....

Specialists Conferences: A World of Innovation 
Feb 22, 2007
At present, there exist numerous platforms for spreading knowledge in a direct and complete manner across the globe, in a way that was never before possible. More specifically, I'm referring to the technical conferences taking place in all fields of technology ...
