A new hybrid Multi Level Inverter to improve the performance of induction motor

The Multi-level Inverter (MLI) drew due importance in medium and high voltage applications. Various conventional topologies have been proposed for the realization of MLIs. However, they suffer from disadvantages such as requirement of more number of components which further increases the complexity to generate control signals and hence the overall cost. To overcome the above disadvantages, a hybrid topology has been proposed in this paper. The performance of the proposed method is compared with the neutral point clamped topology in MATLAB-SIMULINK environment. The result illustrates the reduction in components required, reduction of complexity of control signals design and improvement in the speed of induction motor.
