New Topology of Asymmtrical Multilevel inverter [15/29 Level]

The unique feature of Multilevel Inverter drawn tremendous advantages in Power Industry. There are new set of features based on Conventional set are used to produce high power, high voltage inverter with multilevel structure for compensation of reactive power. Multilevel structure reduces device voltage stress in the structure. In given structure, the device can increase the Power ratings by increasing the no. of steps without increasing the device ratings. With increasing the steps harmonic content reduces without the use of transformer or without the use of series connected synchronized switching devices. It means as the voltages level increases, harmonic content of output level decreases significantly. In our paper, we produce new topology for producing 15129143… Level output voltages from our Voltage Source Inverter Topology. For generation of Multistep, Multiple Pulse Modulation ‘MPM’ & Sinusoidal Pulse Width modulation ‘SPWM’ are used in our topology. In Conventional methodology, Diode Clamped MLI, flying capacitor MLI & Cascaded Inverter topologies are used. In comparison of Conventional topologies, our topology achieve higher no. of output voltage steps with reduced no. of switches, reduced no. of Diodes & reduced no. of Sources. With the reduction in no. of switches & Sources reduce the Size; Cost & Complexity of System reduces with enhancing the performance of overall system. Simulated Design of our topology has been carried in MatlablSimulink 2013a.
