Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

A high-capacity DC/DC converter with novel input-series-input-parallel output-series connection and with autonomous power sharing between modules is proposed. The proposed scheme is well suited for large-scale wind farm DC collection networks, as it avoids the charging current issues associated with its AC counterpart, and offers lower losses and reduced size and weight when a medium- or high-frequency transformer is used. Small-signal analysis is used to derive the control structures for the converter input and output stages. The proposed control scheme is validated through simulation and experimentation, including demonstration of autonomous power sharing between modules under several operating conditions.
