This paper presents the Multi-level pulse width-modulated (PWM) inverters gained increased interest in therecent past years. Three-level inversion is realized with dual two-level inverters in cascade in the proposedconfiguration. An isolated DC power supply is used to supply each inverter in this power circuit each DC-link voltage isequal to half of the DC-link voltage in a conventional NPC three-level inverter topology. The proposed inverter schemeproduces 64 space-vector combinations distributed over 19 space-vector locations as compared to 27 combinations in aconventional three-level topology. A space-vector based discontinuous PWM scheme is used for experimentalverification of proposed topology.
