Rudy Severns Snubber Circuits Switches play a major role in efficient power conversion and have a long history of use beginning with mechanical switches in the 1840's,vacuum and gas discharge devices during the first 60 years of the 20th century, through to today's wide variety of semiconductor devices. While switching device technology has changed dramatically over time, the need to use some form of auxiliary circuit to reduce switch stress and/or losses has been constant. In fact some of these auxiliary circuits, which are often referred to as "snubbers" or "switching aids", are the same today as they were in the 1850's, using the same components, in the same way, for the same reasons. Of course there have also been many new ideas as switch technology has evolved. Despite this long history, new and useful snubber variations still continue to appear. We still haven't invented everything when it comes to snubbers.
