Multilevel inverter topologies (MLIs) are progressively being used in medium and high power applications. This is mainly due to their advantages such as low power dissipation on switches, low Total Harmonic Distortion (THD) and low Electro-Magnetic Interference (EMI) at the output. In this paper, a new Multi-Level Inverter (MLI) topology is proposed. This topology consists of two conversion cells such as Level Generating Cell (LGC) and Polarity Generation Cell (PGC). The basic level generation cell consists of a series combination of power switches, power source and a diode in parallel with both switch and a source. This series combination of such cells generates N-1 levels excluding zero levels. This paper focuses on the reduction of the Total Harmonic Distortion (THD) and calculate the effective switching angles to achieve minimum THD using Equal area criterion and Genetic Algorithms and a comparison is also made between the two methodologies. Simulation model (designed in SIMULINK) is developed and the THD in all cases have been identified. The hardware of proposed seventeen level inverter is implemented and the results are compared and analysed.
