Abstract: The main objective for a grid‐tied Photo Voltaic (PV) inverter is to feed the harvested energy from PV panel to the grid with high efficiency and high power quality. This paper reveals a novel modulation scheme called single carrier Phase Opposition Disposition (POD) Pulse Width Modulation (PWM) technique for H Bridge Multi Level Inverter topology for the solar plants that can account for voltage profile fluctuations among the panels during the day and the performance is studied by comparing total harmonic distortion and switching losses at different switching frequencies. The operating principle and performance of the proposed inverter is verified through simulation studies.
Keywords: PV System, Pulse Width Modulation, THD, Simulation.
