Abstract: In this paper, the envisaged system benefits from both components, reducing the harmonics and the catastrophic failure of the converter and improving the conversion stability of the system. At almost the same time probably, the SVPWM technique for simulating the proposed topology in the MATLAB / SIMULINK platform is used. In order to evaluate the performances of each set, a simple and straightforward distortion harmonic factor is termed that once again simply takes the first two most substantial harmonics present in the generated waveform into account. Two individual phase pattern removes all odd harmonics as well as 3-phase counterparts, which still eradicate non-triplen odd harmonics from the line-to-neutral pattern but instinctively remove such harmonics in line-to-line with the help of selective harmonic PWM elimination (SHEPWM). Thus, the hybrid PWM must ensure a smooth switch between space vector PWM methodologies and the selective harmonic removal PWM. The power quality of the grid under SVPWM and SHEPWM was assessed using the evolved simulation model in Matlab / Simulink. Photovoltaic system modelling includes SPV array modeling, inverter / convertor power electronics predicated on MATLAB / SIMULINK.
