High power, high-boost, resonant-type DC-DC converters as power interfaces for interconnecting wind generators to main grids from MV DC collectors: Design and performance evaluation in steady state

This paper presents two resonant boost DC-DC converters. Both soft-switched configurations can be used to applications in DC grids and have high voltage-gain. These converters are designed to operate as a converter station at the wind generation-side of a HVDC-system linking wind power generation into the transmission network. At initial sections the proposed converters are thoroughly explained. At final sections the steady-state response of voltage and load variations are evaluated for both converters.
