Now days Multilevel inverters are widely used for high-voltage applications due to lesser harmonic distortion, lower electromagnetic interference and larger DC link voltages. Due to this their performance is profoundly better than regular two-level inverters. Nonetheless certain drawbacks as adding in number of components and voltage balancing problems are faced. To overcome these factors, a seven-level hybrid inverter has been proposed. This topology requires lesser power controls which helps in the drop or lessening of its adroit nature, also using PWM generator hence amount to the price and mass of the inverter. The new topology can produce near sinusoidal potentials and better fundamental frequency switching. The simulation and the experimental results of a modified cascaded seven level H bridge inverter one with and one with no LC filter are presented for validation.
