“…The major disadvantage of the conventional power supply of the synchronous machines based converters with thyristor is that it generates a high waveform of the electromagnetic torque. To solve the problem, we proceed to an MSSD whose windings are shifted by 30 degrees by another powered by multilevel converters [5][6].…”

This paper investigates a dual star synchronous machine powered by two independent threelevel voltage source inverters integrated in a wind turbine system (Figure 1). The dual star synchronous machine is used in areas of high power industrial applications such as naval propulsion, traction systems and renewable energy. This use is motivated by several important advantages compared to classical three-phase machine. In this work, the machine side converters control the dq component current by a conventional method based PI regulator, and then the load side converters control the DC bus voltage using sliding mode approach and the RMS voltage load. The validity of the proposed control technique is verified by Matlab/Simulink. Simulation results presented in this paper confirm the validity and feasibility of the proposed control approach, and can be tested on experimental setup.
