In this paper, an experimental verification of the control of a modular series connected voltage source converter suitable for an HVDC transformerless offshore wind turbine is presented. The test bench is built around a 45 kW special generator prototype with three stator segments. Three 20 kW voltage source converter modules were used in the series connected converter. The experimental results verified the feasibility of a modular, decoupled control system design approach which has earlier been investigated through simulations. In addition, the experimental results are compared to simulations to verify the model implemented in EMTDC/PSCAD.
