The goal of the project is to improve the efficiency of converters for wind turbines, particularly in partial load conditions. Compared to the current state of the art, the project aims to reduce the switching losses of power semiconductors, their conduction losses at low current, and the losses in inductors.

In the first phase, various two-point and multi-point converter concepts will be theoretically explored. One promising two-point and one multi-point converter will then be realized as functional prototypes, allowing the performance and efficiency advantages to be experimentally validated.

In the sub-project at the University of Rostock, the converter concepts will initially be compared through design calculations and simulations. For the selected concepts, the control and regulation will be tested on model converters. Additionally, the load-switching stability of board-mounted converters will be investigated.
