During the last decade many new concepts have been proposed for improving the performance of power MOSFETs. The results of this research are dispersed in the technical literature among journal articles and abstracts of conferences. Consequently, the information is not readily available to researchers and practicing engineers in the power device community. There is no cohesive treatment of the ideas to provide an assessment of the relative merits of the ideas. qAdvanced Power MOSFET Conceptsq provides an in-depth treatment of the physics of operation of advanced power MOSFETs. Analytical models for explaining the operation of all the advanced power MOSFETs will be developed. The results of numerical simulations will be provided to give additional insight into the device physics and validate the analytical models. The results of two-dimensional simulations will be provided to corroborate the analytical models and give greater insight into the device operation.If the low-side power MOSFET is turned on by the control circuit, the current flow occurs with a voltage drop determined by the ... input AC power to a DC bus voltage and then use an inverter stage to produce the variable frequency output power [11]. The circuit diagram for a threephase motor drive system is shown in Fig.
