Machinists have a lot of neat shop tricks, but one especially interesting one is shrink-fitting tools. Shrink-fitting achieves an interference fit between tool and holder by creating a temperature ...

[Skyy] sent us a video of him cooking s’mores with an electric arc. He’s using a flyback transformer with a zero voltage switching (ZVS) driver. This produces about 50 kV, which is more than enough to ...

Zero voltage switching in power-conversion applications holds the key to efficiency improvements. Here we look at how ZVS-based designs can deliver those improvements across the widest possible load ...
