Abstract
An industrial application requires a wide range of voltage and power levels. Inverters based on multilevel structure are most preferable in medium voltage and high power applications nowadays. Power quality defines the life of the equipment; hence, major attention is given for reducing harmonic component in an output. Also, constraints of space in industry demand compactness among the devices. This work mainly focused to generate output with minimal harmonic content and minimum power losses with reduced number of switches with level shifted (alternate opposition and disposition) control technique at lower switching frequency. Twelve switching devices are used to generate twenty-seven level output. These twelve switches are used in such a way that two opposite switches are complimentary in nature. This will reduce the requirement of driver circuits. Only six drivers are enough to drive twelve switches making proposed inverter compact. The simulation has been performed in MATLAB/Simulink software platform for testing performance of proposed inverter.
