Efficient modelling of enhanced space vector pulse width modulation for single phase cascaded multilevel inverter and its implementation in fpga

Abstract

Increasing demand in power requirement and power quality is been newlinethe primary need of the hour. This power requirement influences the need of newlineusing renewable source as an alternative for exhausting fossil fuel power newlinegeneration system. While focusing on renewable energy source, the newlinesustainability of power quality at the receiving end seems to be a major newlineproblem. Multilevel inverter combined with solar photovoltaic panel provides newlinegreater help in catering the need of power quality and power demand newlinesimultaneously. Focus on multilevel inverter combined with solar newlinephotovoltaic panel can result in building up a standalone power generation newlineunit which delivers quality power.The research work is directed towards finding a new algorithm for newlineswitching the H-Bridge inverter which converts the solar based DC power to newlinethe AC utility power. In recent years, the digitalization of switching pulse newlinegeneration for a inverter gains more advantage because of the invent of fast newlineswitching devices. Space Vector Pulse Width Modulation technique is newlinecommonly preferred for digital implementation because it offers superior newlineperformance over other Pulse Width Modulation techniques in terms of lower newlineTHD, switching loss and better DC bus utilization. The setback in Space newlineVector Pulse Width Modulation technique is that it involves complex newlinecalculation and hence its digitalization frames complex circuit newline newline
