The industrial and utility sector perceives a shift in the paradigm of technology moving with at a very fast pace with the advent of applications like AC drives, FACTS devices, uninterruptible power supplies and many more. These applications are based on power electronics utilizing voltage source inverters (VSIs) dependent technology. The VSI based applications embodies some of the most pertinent and corroborated up gradation to cater the new challenges existing today. The essence of this paper is to draw attention towards benefits and limitations of using four switch three phase voltage source inverter (FSTPVSI) and present a comparative analysis based on technical, economical and performance parameters with six switch three phase voltage source inverter (SSTPVSI) for industrial applications. Finally, after visualizing the wide scope of research in the field of FSTPVSI, an effort has been made to simulate the both FSTPVSI & SSTPVSI using SIMULINK environment. Numerous design aspects based on technical and economic aspects demonstrate that by slightly modifying the pulse width modulation technique comparable results can be achieved from FSTPVSI topology.
