An IGBT features a significantly lower forward voltage drop compared to a conventional MOSFET in higher blocking voltage rated devices, although MOSFETS exhibit much lower forward voltage at lower current densities due to the absence of a diode Vf in the IGBT''s output BJT. As the blocking voltage rating of both MOSFET and IGBT devices increases, the depth of the n- drift region must increase and the doping must decrease, resulting in roughly square relationship de

To get the IGBT in the forward blocking mode, we need to set a positive voltage on the collector with respect to the emitter and put zero
To get the IGBT in the forward blocking mode, we need to set a positive voltage on the collector with respect to the emitter and put zero voltage on the Gate terminal.
Typically, the IGBT gate drive voltage should be within the 12-15V range, with 12V being the optimal value. During shutdown, a negative bias of approximately -10V is recommended to
