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.

This paper presents an evaluation study of two pwm techniques applied to a three-phase voltage source inverter supplied by photovoltaic (PV) energy sources. A Pspice-based model of the pv array is developed and tested. The power and currant of the pv array versus the voltage is plotted. Then the pv array is connected to a basic three phase voltage source inverter VSI. Two control techniques are used. The first one is the classic sinusoidal pulse width modulation spwm, which is based on the comparison of two signals, the sinusoidal reference and a triangular carrier. The second one is based on the principle of harmonic elimination. The system is simulated using orcad-pspice, the results are given, discussed and compared based on different performance indices (output quality, thd, frequency).

The model of a three-phase voltage source inverter is examined based on space vector theory. SVPWM offers an improved outcome with the inverter as compared to the conservative SPWM technique for the inverter. There is a 15.5% upsurge in the line voltage of the inverter. SVPWM better exploits the available DC-link power with the SVPWM inverter. It has been revealed that the SVPWM method utilizes DC bus voltage extra competently and produces a smaller amount of harmonic distortion and easier digital realization in a three-phase voltage-source inverter. For converter‘s gating signals generation, the space-vector pulse width modulation (SVPWM) strategy lessens the switching losses by restricting the switching to two-thirds of the pulse duty cycle. A hypothetical study regarding the use of the SVPWM the three-level voltage inverter and simulation results are offered to prove the usefulness of the SVPWM in the involvement in the switching power losses lessening, output voltages with fewer harmonics. Nevertheless, despite all the above-cited benefits that SVPWM enjoys over SPWM, the SVPWM technique used in three-level inverters is more difficult on account of a large number of inverter switching states. The attained simulation outcomes were satisfactory. As prospects, future experimental works will authenticate the simulation results. A software simulation model is developed in Matlab/Simulink.

This paper proposes the modified space vector pulse width modulation (SVPWM) control algorithm for the three-phase voltage source inverter (VSI), which consists of traditional six switches VSI and three bidirectional switches for creating the ac decoupling circuit. This topology has some advantages such as the ability to reduce the leakage ground current from PV panel and therefore improve the efficiency of photovoltaic (PV) energy conversion based on the principle of decoupling when the zero space vectors occur. Likewise, no current flows through six traditional switches in zero space vectors, thus they operate at lower average temperature. In this case, the conduction losses are reduced. For avoiding shoot-through states between six traditional switches and three bidirectional switches, a delay time has been added to switching time and managed carefully to guarantee THD of output voltage. Operating of the inverter with the modified SVPWM method is simulated by using Matlab/Simulink software and implemented in the experimental prototype by using FPGA Virtex 5 (Xilinx).
