Poly-phase systems have been used for many years in machines and recently in wind power generations. They usually are built by a dual three-phase system, shifted by 30 electrical degrees from each other and with no neutral connection. Typically, this system employs a twelve-pulse diode rectifier to converter ac to dc voltages. However, it may be improved if an active rectifier is used, because it can provide lower distortion in generator currents and regulated output voltage. Taking that into account, this paper proposes a six-phase active rectifier topology for a dual three-phase system. A stationary frame reference for six-phase system is applied to obtain the converter dynamic model in the αβ coordinates and thus a control strategy is proposed in this frame reference. The proposed topology, dynamic model and control strategy were verified by simulation for following specification: 12 kW, 220 V at input voltage and 800 V at the output voltage. The results were appropriated, providing a regulated output voltage, an input current with reduced harmonic distortion and thus high power factor.
