Thermal influence in the design of DC to AC converters due to climatic change for photovoltaic solar plants

Abstract

This research article discusses the impact of climatic changes in South America, with a case study in a tropical zone, particularly the rise in temperature by 1.15 °C from 1998 to 2022, reaching a maximum of 45.85 °C in 2023. Focusing on the Electronic Conversion Unit, especially IGBT efficiency during El Niño-Southern Oscillation phenomenon in 2023. The case study employs finite element analysis using Navier Stockes-Boussinesq equations, it evaluates the heat dissipation, airflow modeling, and temperature effects, the research proposes enhancements like redesigned air flow grids, centralized air filters, and wind fans. Implementing these improvements reduces the temperature by 5.6 °C, enhances airflow speed, and mitigates the climatic impact on electronic devices over the next two decades.
