Inductive Devices in Power Electronics

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.
