KurzbeschreibungPower semiconductor devices are the core of today's energy efficient electronics. In this course, based on semiconductor physics, an understanding of the functionality of modern power devices is developed. Elements of power rectifiers and switches are introduced; device concepts for PiN diodes, IGBTs, and power MOSFETs, are discussed. Apart from silicon, wide bandgap semiconductors are considered.
LernzielThe goal of this course is developing an understanding of modern power device concepts. After following the course, the student will be able to choose a power device for an application, know the basic functionality, and is able to describe the performance and reliability related building blocks of the device design. Furthermore, the student will have an understanding of current and future developments in power devices.
InhaltBasic semiconductor device physics is revisited. After defining requirements from typical applications, the key building blocks - especially active area and termination - of power devices are introduced. Based on these building blocks, device concepts are derived. Introducing unipolar as well as bipolar conduction is increasing the application space for power devices. Rectifiers, such as Schottky barrier and PiN diodes, and switches, such as IGBTs and power MOSFETs are discussed in detail. For each device concept, a tradeoff analysis for performance and reliability based on the layout of the building blocks is discussed.
Apart from silicon, wide bandgap semiconductors play an increasing role for highly efficient power electronic devices. This development is taken into account by discussing the specific advantages and challenges in current wide bandgap based devices.
