Hello everyone, so I'm currently trying to find out how much power will be lost during reverse recovery of a MOSFET's diode. I'm using this paper for reference, https://www.fairchildsemi.com/application-notes/AN/AN-6005.pdf the equation they end up with is P= Qrr*Vin*Freq_sw the problem is, for my application this gives an enormous number with the MOSFET I'm using. I have: Qrr = 1.9uC Vin = 380V Freq_sw = 100,000Hz which gives us a total power loss of 72.2W. My question is, does this seem right? I can't believe that almost 100 watts will be lost in just the reverse recovery process... Any help is greatly appreciated!
