Increasing current densities and short switching times in MOSFETs are placing ever greater stress on the dielectric strength of inductors. Molded inductors with a distributed air gap based on iron powder enable high inductance values in the smallest of spaces and thus increase the power density. A new test con

Welcome to the March issue of Power Systems Design Europe. As I’m sure I mentioned in this page last month, I shall be making my first trip to the APEC Exhibition to have a look at some of the innovation in the power industry that is happening on the other side of the Atlantic. I’m really looking forward to

It’s here! At long last! The Kansas City Chiefs and Philadelphia Eagles might’ve clashed in early February, but with respect to the NFL, March brings us the true Super Bowl, the biggest event of the year for power electronics.
I speak, of course, of the Applied Power and Electronics Conference (APEC), w
