Space Vector PWM Technique for a Direct Five-to-Three-Phase Matrix Converter Conference Paper uri icon

abstract

  • This paper proposes space vector pulse width modulation (SVPWM) technique for a direct matrix converter with five-phase input and three-phase output. This topology of matrix converter is developed exclusively for feeding three-phase stiff grid system with five-phase variable input supply. One of the presumed applications is wind electric energy generation system. The paper presents the complete space vector model of the five-to-three-phase matrix converter topology. The major breakthrough of the proposed control scheme is the enhanced input to output voltage transfer ratio. The maximum output phase voltage can go up to 104.4 % of the input phase voltage in the linear modulation range and hence can act as a boost converter. The space vector model yields 215 total switching combinations, which reduce to 125 states (for SVPWM implementation) considering the imposed constraints, out of which 120 are active and 5 are zero vectors. However, for SVPWM implementation only 30 active and 5 zero vectors can be used. A generalized formula for maximum modulation index for n-phase input and 3-phase output is also formulated. The SVPWM algorithm is presented in the paper, and the viability of the proposed solution is proved using analytical, simulation and real-time approach. © 2013 IEEE.
