Since their introduction in the early 1980s, silicon Mosfets have been the mainstay of power conversion technology, in particular for high frequency switching power convertors. The device technology has evolved over the decades, from planar to split gate trench and superjunction platforms. Far from being obsolete or stagnant, innovations continue steadily in silicon technology.
This seminar will cover characteristics of state of the art, high performance Mosfets using their datasheets as reference. Instead of explaining away datasheet numbers line by line, we will be grouping them functionally, explain how they are characterized by the manufacturers and how they should be interpreted for real world applications. Unique features such as extremely nonlinear capacitances and body diode behavior will be discussed in depth. Mosfet datasheets carry a number of legacy parameters, specifically those relating to current and power ratings, that are no longer relevant in today’s design environments. These will be highlighted during the course.
Recently there has been an explosive growth in power applications other than high frequency switching, such as motor control and automotive electronics. The seminar is aimed at Mosfet users in all these application areas and will be useful to engineers both at the beginner and intermediate levels.
