Development Of A Modified Svm Algorithm For Controlling The Rec Z-Source Npc Inverter
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 1
Abstract
The REC Z-source NPC inverter is accepted to come across applications in grid connected distributed generation (DG) systems based on renewable energy sources such as photovoltaic systems, wind turbines and fuel cell stacks. Two DG systems can be connected to the grid with only one REC Z-source NPC inverter thus plummeting the volume and cost while rising efficiency and facilitating control. The modulation of the REC Zsource NPC inverter was described using the carrier-based approach. However the space vector modulation (SVM) approach offers better harmonic performance compared with carrier-based pulse width modulation (PWM) strategy without zerosequence voltage injection and can more expediently handle overall switching patterns and constraints and it is simple to implement.
