Abstract: The technology introduces a DC linked multi-level inverter topology to raise level of the efficiency and power factor. It consists of four active and four DC link switches for a proposed 5 level inverter .The number of level can be increased to 9, 13 and more levels as required. It uses a Phase Opposition Disposition method with a single carrier to control the switches.
Keywords: Multilevel inverter, Total harmonic distortion, DC links switches, Single carrier.
