A differential unipolar trailing edge modulated boost inverter for solar applications

The demand for clean energy is increasing daily due to the depletion of fossil fuels. Solar energy is considered as one of the promising green energy source for the future generation. This paper uses solar energy as power source. The solar power is processed by a novel power conversion system and given to the AC load. The suggested system includes a stand-alone photovoltaic system, Battery, Sinusoidal inverter, unipolar trailing edged PWM controller and AC load. This system serves pure sinusoidal output for the AC load thus extending lifetime of the load equipment. For blending an inverter into a system, one has to follow a very vital guideline of limiting THD lesser than 5%. THD represents the amount of total harmonic content present in output current. This paper focuses on minimizing THD by providing an inverter with minimized output current THD. The advised inverter overcomes many demerits exhibited by traditional and existing inverters. The designed system will provide 48Vmax AC voltage with highly diminished harmonic content for an input of 48V DC. The complete system was simulated in MATLAB SIMULINK and hard ware experimentation has been conducted with dSPACE-1104 real time interfacing kit. The hardware and simulation results have been presented for further analysis.
