OST – Power Electronics Laboratory

The Power Electronics Laboratory at the OST was established in 2008 and offers comprehensive expertise in the field of switched mode power conversion. One of the focuses is placed on battery charging for electro mobility and stationary applications.

In modern energy systems, power electronics has gained a great deal of importance over the last decade. The demand for ever-increasing charging/discharging power ratings of battery systems poses great challenges on power electronics. This can only be met with novel topologies combined with new semiconductor device technologies.

We have placed a particular focus on wireless power transfer WPT. For electric vehicles, WPT systems offer a number of advantages, such as ease of use for the operator, no conductive parts between the electric systems of charger and vehicle enhance safety, and no wear-out of mechanical parts increase reliability.

The Power Electronics Team offers the following services:

Feasibility studies for power electronics components and systems using analytical methods and simulation tools.
Development of switched mode power converter hardware and related software, while employing the latest technology.
Realizing, optimizing and testing hardware from early evaluation models to advanced prototypes.
Development of WPT systems, which includes electrical and magnetic modelling, analytical optimization using 3D-FEM tools, constructing the hardware and final characterization and verification.
