Focus Topic 5
Emerging Power Electronic Devices
SiC MOSFET Gate Drivers for High-Power Applications
- Drazen DUJIC, École Polytechnique Fédérale de Lausanne (EPFL) – Power Electronics Laboratory, Switzerland
- Chengmin LI, École Polytechnique Fédérale de Lausanne (EPFL) – Power Electronics Laboratory, Switzerland
As the next-generation power devices, SiC MOSFETs are gradually increasing their presence in a wide range of applications. Compared with the silicon counterparts, SiC MOSFET has higher voltage blocking capability, high switching frequency and potential high-temperature capability. These superior characteristics will significantly improve the performance of power conversion systems where efficiency and power density are the most critical performances. As the link between the control and power in the power electronics system, gate driving of SiC MOSFETs is critical to fully utilize the potential of the devices. However, simply leveraging solutions for Si devices are not enough. The challenges brought by high-speed switching, reliability-related issues and cost constraints require continuous work. This tutorial covers the basics of the SiC devices, the ultra high-speed switching characteristics, the gate driving principles and device protections, as well as the high power applications of SiC MOSFETs. This will be supported by practical examples and learnings of the authors at Power Electronics Laboratory at EPFL.
TUTORIAL N° 16
(09:30 – 13:00)
New Advances and Trends on Model Predictive Control for Power Electronics and Electrical Drives
- Marco RIVERA, University of Nottingham, United Kingdom
- Pat WHEELER, University of Nottingham, United Kingdom
In the last decades, fast modern microcontrollers have been continuously growing, allowing the development and implementation of new and more intelligent control strategies as an alternative to conventional techniques for power converters. Model Predictive Control is one of these powerful and attractive alternatives that has received special attention in the last time. The use of predictive control offers several interesting advantages: it is an intuitive control approach, it does not need linear controllers and modulators, and it is possible to easily include nonlinearities and restrictions in the control law. It can be expected that the advantages of predictive control will lead to industrial applications in the future after some further progress. In this tutorial new advances and trends of model predictive control for power electronics and electrical drives will be presented.
