The MOSFET (metal -oxide semiconductor field-effect transistor) is a near-ideal three-terminal component used for linear and switching applications. After a brief overview of the MOSFET's internal structure and operation, this course looks at critical and relevant device parameters to consider when using MOSFETs in their most common switching applications, such basic AC-line control, power-supply design, and motor control (via H-bridge and other topologies).

Among the parameters explored are on-resistance, switching time, and thermal performance. The course will also explore important associated issues such as the MOSFET driver and driver requirements (including isolated versus non-isolated drive), circuit protection, packaging, and paralleling MOSFETs, plus design issues and potential problems to take into aware of.
