MOSFETs BasicsMOSFETs BasicsMOSFETs (Metal Oxide Semiconductor Field Effect Transistors) have been usedin power electronics applications since thee early 80's due to theirappreciable current carrying and off-state voltage blocking capability withlow on-state voltage drop. They have managed to replace BJTs in manyapplications due to their simpler gate drive requirements and higherpositive temperature coefficient which allows devices to be paralleled forhigher current capabilities. 1. IntroductionA number of different types of MOSFET are produced which have slightlydifferent operating mechanisms and characteristics. Figure 1 graphicallyillustrates the differences between the four different types. [pic] Figure 1: The steady state characteristics of diff……
