Reduced matrix converter operated as current source for off-shore wind farms

Converter topologies for offshore wind farms must be designed taking into account reliability and size of the converter. Reduced matrix converter fulfill this two requirements and permits to built a series connected grid. The modulation of this converter can be done by space vector or carrier based modulation. Both types of modulations must be modified to accomplish the requirements of the three phase to single phase conversion. This paper analyzes possible modified modulations from the losses point of view. The converter is operated as current source converter. Simulations were carried out using PSIM and a dynamic link library programed in c++ for the losses calculation.
