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.
