A novel PWM scheme for grid-tied inverter in micro-grid with enhanced power quality using silicon cells

Abstract This paper presents a cost effective solution to reduce harmonics and improved power factor in grid tied inverter by varying the control pulses instead of using hardware components like filtering and multilevel inverter. A two-level inverter is taken for simulation study and a new pulse width modulation method is proposed by tying altered space vector pulse width modulation method and hysteresis current control. This novel scheme provides low harmonic content, improved power factor, enhanced power management, enriched storage and maxim extraction of power. The simulation work of grid-tied inverter integrated with micro-grid is carried out with MATLAB/Simulink 2018 and the performance of the proposed novel pulse width modulation approach is analysed in terms of harmonics content in output current.
