Matlab-Simulink

Space vector pulse width modulation (SVPWM) is a superior switching technique offering several benefits for power electronic inverters. However, concerning multilevel inverters (MLIs), implementing SVPWM is a demanding and time-consuming task because it deals with the six sectors of the space vector modulation (SVM) plane and numerous regions and vectors. Several research works in the literature tried to simplify SVPWM implementation for MLIs.

Models of the electrical machines are used in the process of development control system and verification of them. Nowadays multiphase machines are attracting attention due to their reliability; however, standard MATLAB libraries are limited by 5-phase and 3-phase models. This paper considers a universal model of 3-, 5-, 6-, 7-, 9-phase permanent magnet synchronous motor. The model was developed using standard blocks of MATALB Simulink and can be used as a component of SimPowerSystem. Simulation results are provided as well as a link to the library for use free of charge.

This work presents the performance evaluation of incremental conductance maximum power point tracking (MPPT) algorithm for solar photovoltaic (PV) systems under rapidly changing irradiation condition. The simulation model, carried out in Matlab and Simulink, includes the PV solar panel, the dc/dc buck converter and the MPPT controller. This model provides a good evaluation of performance of MPPT control for PV systems.
