In this paper a new single phase seven and eleven level inverter based on a tap changer transformer is developed to generates seven and eleven non-equal voltage levels from two DC sources. The model of inverter thus presented does not suffer from voltage balancing issues. The DC sources are connected to the primary side of the tap changer transformer with the help of a microcontroller circuit (Arduino UNO), with several semiconductor switches offering sequential modality. At the secondary side of transformer, the output voltage is generative, and Proteus/Software manipulation is performed. This technique reduces the Total Harmonic Distortion (THD) of the output voltage significantly.
