Now days Power electronic inverters are becoming trendy for various Industrial drives, UPS, HVDC transmission system & Induction heating. Bipolar inverter Are less efficient, costly, and high switching losses. To overcome these demerits, Multilevel Inverters are used. The Multi-level inverter output voltage response having a smaller number of harmonics compared to output voltage of the unadventurous bi- polar inverter. As Voltage level increases, number of power semiconductor switches also increases. It further increases cost, size and complexity in control. To obtain higher level of voltage with number of switches reduce, new multi-level inverter topology with reduced number of power semi-conductor switches is obtainable. The Multilevel Inverter proposed here uses a smaller number of switches compared to conventional topologies. Hence provides lower switching losses and economically advantageous unit than conventional cascaded H-bridge inverter. The topology suggested here is simulated using level shift and phase shift carrier pulse width modulation technique.
