Abstract
This project present a study of cascaded H-bridge multilevel inverter based on supercapacitor to reduce harmonic for high power applications.Applications of multilevel converters are able to reduce the number of harmonics contained in the system of electrical network. This study deals seven-level cascaded H-Bridge multilevel inverter with sinusoidal pulse width modulation (SPWM)controller and two type of energy storage comprises of supercapacitor and DC supply for reduction of the harmonic in the electrical network. This paper also deals with simulation of seven-level cascaded H-Bridge multilevel inverter in MATLAB/SIMULINK environment.The proposed system designed using MATLAB/SIMULINK consists of a supercapacitor and DC supply as energy storage.The controller based on sinusoidal pulse width modulation was applied to the inverter.The design to change the modulation index from 0.5 to 1.0 also is used at controller to monitor the supercapacitor performance to reduce the harmonic is also discussed.The various performances of simulation results between super-capacitor and DC supply have been investigated.The Total Harmonic Distortion (THDv) of the inverter output voltage is measured where two types of energy storages (DC supply and super capacitor) are applied to the inverter input. It can be observed that the THD voltage output of the inverter for the super capacitor is considerably lower than the DC supply that is exceed 90% and meet the needs of supercapacitor considered low at 5% as specified by IEEE 519 standard on harmonic distortion level.
