Control Scheme to Precharge the DC-Link of a Hybrid Transformer AC/AC Converter
In this thesis, you will develop a control scheme to precharge the DC-link of the HT AC/AC converter. The development of the control scheme and the analysis of the AC/AC back-to-back converter will be based on simulations in MATLAB/PLECS.
Keywords: Hybrid Transformer, Smart Grids, Modeling and Control, Back-to-Back Converter, Power Electronics Converter
In the future, an increase in renewable energy generation is expected.
Therefore, new grid components are required, which enable a more flexible
and smarter power flow control in the grid. Hybrid power transformers, as
shown above, are an example for such components.
At HPE, a hybrid transformer (HT) concept is investigated for the medium
voltage level distribution grid. An AC/AC converter is a key element of
such a HT. In this case a bidirectional HT AC/AC converter is chosen, for
which a control scheme during the start up of the HT AC/AC converter
needs to be developed and investigated.
In this thesis, you will develop a control scheme to precharge the DC-link of
the HT AC/AC converter. The development of the control scheme and the
analysis of the AC/AC back-to-back converter will be based on simulations
