A snubber for electric circuits comprises a plurality of small lossy magnetic cores with a wire through each, wired in parallel. Such an arrangement will have a much faster saturation time than a single core of comparable volume, and the power dissipated will be distributed and have more surface area. With conventional lossy snubbers, the only choices are the size of the core and the material. With this snubber, the number of cores to use, and the size of the individual cores are additional variables available to the designer to optimize the snubber. A variation of the snubber uses a plate of lossy magnetic material with a plurality of through holes. This is comparable to using individual cores, but the one piece may be easier to handle and assemble.
