In this paper nine level Hybrid H- Bridge Multilevel inverter is analyzed for the various multi-carrier Pulse Width Modulation strategies. For the same nine level inverter output this particular topology has reduced count of switches, on comparing with the conventional Cascaded H Bridge Multilevel Inverter. For a single phase, nine level inverter output this topology requires one H-bridge and a half Bridge cell with Four equal voltage sources. Instead of sixteen controlled switches as in conventional method, this topology requires only twelve switches to obtain nine level output. The reductions in components count lowers, cost and complexities. Performance parameters have been analyzed for the nine level Hybrid H Bridge Multilevel inverter.

Abstract
In this paper nine level Hybrid H- Bridge Multilevel inverter is analyzed for the various multi-carrier Pulse Width Modulation strategies. For the same nine level inverter output this particular topology has reduced count of switches, on comparing with the conventional Cascaded H Bridge Multilevel Inverter. For a single phase, nine level inverter output this topology requires one H-bridge and a half Bridge cell with Four equal voltage sources. Instead of sixteen controlled switches as in conventional method, this topology requires only twelve switches to obtain nine level output. The reductions in components count lowers, cost and complexities. Performance parameters have been analyzed for the nine level Hybrid H Bridge Multilevel inverter.
Author Keywords: alternate phase opposition disposition, Hybrid H-Bridge Multilevel Inverter, phase disposition, phase opposition disposition, phase shift pulse width modulation, sinusoidal pulse width modulation.
