Now a days the growth of interest in multilevel inverters has been increasing because there are enormous applications of there in FACTS and industrial drives etc., Although there are many topologies of multilevel inverters in literature, popular among them are cascaded H-bridge Inverters plays vital role in routine life. Harmonic content of output voltage can be decreased considerably by switching methods. Describes a harmonics reduced in a hybrid cascaded multilevel inverter circuit with new pulse width modulation (PWM) scheme. These scheme pulse width modulations in proposed method are uses reduce switching device. Then to reduced the switching losses and also reduced the harmonics in an inverter circuit. These methods are a combination of a conventional inverter and h bridge inverter. Both inverter are combined a new five level hybrid cascaded multilevel inverter. The multilevel carrier based pulse width modulation methods are used in this topology a Five level output voltage wave forms is shown in FFT window. MATLABE/SIMULINK is used to simulate the inverter circuit operation and control signals.
