The next great frontier in power supply design is magnetics. Decades of investment in semiconductor technology has given us a wide array of almost-perfect switches, but to take full advantage of this, we are going to need new technology for the inductors and transformers. Who is going to do this work? Will it be the magnetics manufacturers or the power supply designers? Manufacturers have a deep knowledge of materials and processes needed to assemble components. However, the circuit designer has an intimate knowledge of all the topologies available, the waveforms and harmonic content. Perhaps the semiconductor companies doing the reference designs have this knowledge or could it be something else? Who is most qualified to assess the performance of new designs? In this lively rap session, we will look at the paths available for future progress. Highly qualified panel members from all sides of the issue will provide an entertaining and informative evening that is not to be missed.
