Dr. Tom Wilson of SIMPLIS Technologies

Abstract:

In SIMPLIS version 9.4, the SIMPLIS MOSFET model extraction process has been improved to accommodate important differences between Si, GaN and SiC devices. This new model extraction process can now automatically handle both 4-terminal and 3-terminal devices. This improved model can also include parasitic lead inductances. In addition, we discuss the importance of modeling MOSFET drivers along with straightforward methods of modeling critical current and voltage limitations of these drivers in SIMPLIS. We will examine an example using a DAB converter to explore switching losses on both the primary-side bridge and the secondary-side bridge as a function of output power and deadtime.
