Investigating the reliability of SiC MOSFET body diodes using Fourier series modelling [PDF]

2014 IEEE Energy Conversion Congress and Exposition (ECCE), 2014
Using the Fourier series solution to the ambipolar diffusion equation, the robustness of the body diodes of SiC MOSFETs during reverse recovery has been studied. Parasitic bipolar latch-up during the reverse recovery of the body diode is a possible if there is sufficient base current and voltage drop across the body resistance to forward bias the ...
