This paper presents the design and control of an advancedunidirectional DC/DC Modular Multilevel Converter (MMC)that facilitate the integration of off-shore windfarms with theHigh-Voltage Direct Current (HVDC) transmission system.The proposed converter deploys a single-phase MMC invertercoupled with series-connected rectifier modules throughmultiple medium frequency transformers. Unlike theconventional d-q control method, which involves multipletransformations, this paper also proposes a simple controlstrategy that directly act on the ac output of the MMC, underthe stationary reference frame.
