Webcoefficient). However, for any IGBT, whether PT or NPT, switching loss is traded off against V CE(on). Higher speed IGBTs have a higher V CE(on); lower speed IGBTs have a lower V CE(on). In fact, it is possible that a very fast PT device can have a higher V CE(on) than a NPT device of slower switching speed. Switching Loss For a given V Web24 aug. 2013 · The switching losses are proportional to the frequency and the time taken to switch the load. In general, the mosfet will be able to switch faster than the IGBT Look at the switching speeds for both devices. (typically a rise time and a fall time) Say they're 17ns and 7 ns. Add these together (24nS of switching time each cycle).
