Off-Grid Power Generation using SEPIC Converter with P&O for PV System

Abstract

A DC-DC Converter single-ended primary inductor converter (SEPIC) converter was proposed in this article, as well as an inverter with a PV source. The key function of this paper is to include two interface circuits: a DC-DC converter and an inverter.It is crucial that the DC-DC converter with Maximal power point tracking (MPPT) be addressed while designing a technique to operate in accordance with the photovoltaic modules and produce a more adept outcome.Perturb and Observe measurement is used as a part of the DC-DC converter to pump up the output voltage of the PV module. Using the inverter, the output voltage is changed to AC voltage. The MATLAB programming was used to finish the job on the SEPIC converter and the inverter.To generate the PWM beats for the SEPIC converter circuit, a DSP controller is used. To decrease corrosion of the transparent conducting oxide (TCO) and to minimise leakage present, the negative terminal of the solar cell is made to bind to the substrate. So it is possible to increase the performance.
