Abstract :

The classical two level inverter produce output with levels either Vdc or -Vdc. The output voltage waveform of ideal inverter should be sinusoidal but the waveform of conventional inverters is non-sinusoidal and contains certain harmonics. Large capacitor is normally connected across the DC voltage source and such a capacitor is costly and demands space. In order to overcome these drawbacks Multi level inverters are introduced. The great advantage of this kind of inverter is the minimum harmonic distortion obtained. Power electronics is the applications of power semiconductor devices for the control and conversion of electric power such that these devices operate as switches. An inverter is an electrical device that converts DC voltage to AC voltage; the resulting AC can be at any required frequency. Multi-level inverters are nothing but the modification of basic bridge inverters [1]. The multilevel inverter collectively converts the several levels of dc voltage to a desired ac voltage. The unique structure of multilevel inverters allows them to reach nearer to sinusoidal i.e., with low harmonics. In this project the work is done on five & nine level multilevel inverter but the multilevel can be done up to any level and how many levels we increase that much precise sinusoidal supply we can get i.e., we can reduce that many harmonics from the supply. Simulation work is done using the MATLAB software [10].
