ABSTRACT: The use of voltage source inverter (VSI) in high performance drives removes the restriction of the number of motor phases. Due to the reported advantages of multiphase machines they have become of increasing interest to the industry. This paper provides a Matlab/Simulink built nphase machine model in terms of physical variables along with the VSI and V/f control scheme that a user can easily set to any phase (n≥3) number. Efforts have been made to produce the simplest model possible, so that a student can easily understand the mathematical model of the machine and relate it to the variables within the Simulink model. After a short theoretical review of the mathematical model of an induction machine with an arbitrary phase number, the Simulink implementation is discussed. Simulation results for a three and fivephase machine are provided, to prove the validity of the model and capabilities of the developed software.Universities Power Engineering Conference (UPEC), 2010 45th International; 10/2010

ABSTRACT: Space Vector PWM (SVPWM) model is often built based on highlevel functions and verified based on the output of the inverter or the model of the electrical motor with best possible accuracy. However, SVPWM implementation on digital hardware such as Field Programmable Gate Array (FPGA) and Applicationspecific Integrated Circuit (ASIC) is constrained by the limited resources and computation accuracy in these digital hardware compared to the mathematical model. The paper proposed a method that utilizes Matlab Simulink and FixedPoint Toolbox to construct hardwareamenable SVPWM model. Using the proposed model, it is possible to estimate the digital hardware resources used and analyze the accuracy of the system before the actual designing process takes place. The model has been simulated and verified with signal switching patterns and output signals from the model of the electrical motor. Based on functional comparisons, it was found that the outputs of the SVPWM model are almost identical to the digital hardware implementation.Circuits and Systems (APCCAS), 2010 IEEE Asia Pacific Conference on; 01/2011  [show abstract] [hide abstract]
ABSTRACT: This paper presents a new simplification of Space Vector Pulse Width Modulation (SVPWM) for twolevel threephase inverters. The lookup tables with formulas about switching times and states were replaced by simple arithmetic and boolean equations. The explicit identification of the sector where the reference space vector is located was also eliminated. This paper proposes the rotation of reference space vector in 180° if its imaginary component is negative. This new procedure reduces the number of sectors to analize. Simulation and experimental results demonstrate that the proposed simplification of SVPWM can achieve the desired voltages and has less computational cost than conventional SVPWM.01/2010;
