Modeling and Simulation of NPC Inverter for Generation of Three Levels Based on LC Switching with ANN Controller

This paper presents a new control scheme for three levels NPC Inverter to boost up the input dc voltage and givethree levels AC output voltage with less harmonic distortion in a single stage.Recently, Single stage highvoltage pick up support inverter is getting ubiquity in applications like sun powered PV, energy component,UPS systems and so on. As of late, single stage voltage support multilevel Z-Source inverter (ZSI) and Quasi Zsourceinverter (QZSI) have been proposed for DC-AC control transformation with enhanced power quality.Multilevel ZSI utilizes more number of high power inactive segments in the middle of the road arrange whichincrement the system measure furthermore, weight. Likewise its info current is irregular in nature which is notalluring in a portion of the applications like energy unit, UPS systems, hybrid electric vehicle and so forth. Inthis paper a consistent current info three level LC Switching based voltage help nonpartisan point clipped (NPC)inverter with ANN logic controller is proposed which utilizes similarly less number of high power detachedsegments at the same time holds every one of the benefits of multilevel QZSI/ZSI. It is ready to help the infoDC voltageand give required three levels AC output voltage in a solitary stage. The ANN logic controller isincorporated to systematically control the time allocation for all the switching states based on instantaneousvoltage. Using the ANN controller for a nonlinear systemallows for a reduction of uncertain effects in thesystem in the system control and improve the efficiency . Enduring state investigation of the proposed inverter istalked about to define the connection between the info DC voltage what's more, three level AC output voltage.The proposed converter with ANN controller has been verified by simulation in MATLA Simulink
