Do We Need to Progress Towards GHz Switching in High Power Systems and Applications?


This was a rap session topic at the Applied Power Electronics Conference 2017 in Tampa, Florida. Continue the discussion here…


You can progress towards GHz switching, but it’s not a free ride. The answer to that question really depends on what you’re trying to achieve. If you want to shrink size / increase power density, sure, but then you’ll deal with much more formidiable challenges such as conducted and radiated emissions. Dealing with these emissions will also consume real estate, so you have a trade-off. In my opinion, the added complexities and considerations would only attract very specialized applications to that switching frequency.
