Multiphase system supplied by PWM VSI. A new technic to compute the duty cycles
Résumé
When multi-phase machines with magnetic couplings between phases are supplied by triangle intersection PWM, there are parasitic currents. To solve the problem, it is necessary to use Space Vector Modulation. A SVM extended to systems with arbitrary number of phases is proposed. Optimization of time computation and consideration of switching constraints have been considered. Experimental results are given for a vectorial control of a 5-phase machine.
