Abstract: The Multi-Level Inverters (MLI) is an essential part of all electrical and electronics device. Most of the electrical equipment’s in our country are run on 50Hz A.C. supply, in this proposed work present a modified hybrid casecade 27 level multi-level inverter for 3 phase A.C. supply. IN the last there are different researchers work on different level MLI inverter such as 7 level, 9 level, 11 level, up to 35 level and got good total harmonic reduction (THD). In this presented proposed Modified Hybrid Case Cade 27 Level Multi Level Inverter obtain good THD value at 27 level 1.82 that is better as compare to other methods. The proposed Modified Hybrid Case Cade 27 Level Multi Level Inverter shows better due to its logical switching pulse. There pulse are use relational operator for comparing waves. For the analysis and performance measurement of proposed MLI apply load that is three-phase asynchronous machine, also known as induction machine at receiver end and got good result in terms of machine's speed and second one is electromagnetic torque developed by the machine. The proposed method good result output of induction motor.
