Control circuits are a key element in the operation and performance of power electronics converters. This book describes practical issues related to the design and implementation of these control circuits, with a focus on the presentation of the state-of-the-art control solutions, including circuit technology, design techniques, and implementation issues.

During the rapid developments in semiconductor technology, the role of inductive components as a limitation for further improvements became clear. The challenges involve the magnetization losses and unwanted eddy currents at higher switching frequencies, which in turn limit the reduction of device volumes. New materials and design approaches offer solutions. Furthermore, new topologies of power converters in connection with flexible digital controls and design of magnetic components offer ways to reduce the required component volume and increase the power density, which is especially important for mobile applications.

This book covers the progress made in the area of wide bandgap semiconductor (WBG) technologies, in particular SiC, with a strong emphasis on their applications torapidly progressing areas such as automotive, aerospace and the whole electrical energy sector. The book is unique in its blend of device functionality and capabilities, technology road maps, as well as addressing the important aspects of real-life applications of these emerging devices. The benefits offered by wide bandgap material devices is enormous, and in the era of more electrification of transport and reformation of the whole energy supply chain this is set to be one of the key defining technologies over the next few decades that will support the whole eco-structure of society in the 21st century, much as silicon has done over the last half of the 20th century.
