Performance Studies on a Multi-cellular Boost Converter Dedicated for Domestic DC Applications (Cooker)

 In this chapter, we outline the design, sizing, and testing of a power system that enables photovoltaic renewable energy to be used to power DC equipment via solar batteries (Cookers, distillers, refrigerators, dryers, …). The suggested system is based on the usage of a multi-cell DC/DC converter of the Boost type that is managed by a microcontroller and produces PWM signals with a 20 kHz frequency and variable duty cycle. The solar batteries (24 V, 520 Ah) store the electrical energy generated by the photovoltaic panels (600 W), which is subsequently transmitted to the application via the suggested DC/DC converter. The maximum temperatures of the heating resistance and the oil are achieved by the fry-cooking system (by hot plate cooker), which exhibits a DC/DC converter efficiency of 84 percent, during trial. After 6 minutes of heating, the oil temperature reaches 100°C, or 16.67°C/min with a cooking duration of around 20 minutes, or temperatures of around 640°C and 230°C, respectively. Approximately 28.72 Ah, or 5.52 percent of the overall battery capacity, is the battery consumption capacity. The economic analysis of the usage of renewable energy stored in batteries and a comparison of all the outcomes with those predicted reveal that the power system suggested in this work works well and is legitimate.
