A 1kW synchronous buck converter for solar powered conduction cooking system in off-grid areas of Bangladesh

摘要

Depletion of Natural Gas and increasing price of LPG, burning wood, coal etc, are now the main menaces for cooking purposes in Bangladesh. On the other hand, inefficient burning of wood, charcoal, agricultural wastes and animal dung etc, generate smoke and emits ozone gases. This results in global warming and health issues due to inhalation of the smoke. Because of a good solar irradiation pattern, a solar powered conduction cooker can minimize this burden from the nation. The purpose of this paper is to design, analyse the prospect and performance of solar powered conduction cooking system by using Thin Film photovoltaic modules with a novel synchronous Buck Converter Controller topology. Physical demonstration was made by installing 1 kW Thin Film PV modules on the rooftop of the university building with setting up the conduction cooker and other measuring equipment. 10 panels of 95 Watt are mounted on the rooftop of the university building. Based on solar irradiation data round the year, projected output is analysed by using PSIM simulation and the prospect of solar powered conduction cooker in Bangladesh is shown with economic feasibility. The system was designed and analysed in PROTEUS software and the hardware was fabricated and implemented. Based on the experimental data, the performance of the system is also analysed and presented in this paper.
