Descriptive Design and Construction of a Hybrid Induction Cooker for Domestic Use in Sub-Saharan Africa

Abstract

This work details the design and implementation of a 24V, 0.48kW, 120kHz hybrid induction cooker that utilizes both solar and grid power sources, prioritizing solar energy. Relying on solar power is advantageous in regions of Cameroon with frequent power outages or no electricity, yet abundant solar irradiance, thereby addressing issues related to conventional cooking methods. The study involved designing various components and circuits necessary for building the system, such as the battery charger and automatic selection circuitry for switching between solar and grid power. Efficiency was evaluated by measuring power input and consumption. The output current and voltage waveforms were analysed to demonstrate the purity of the high-frequency alternating current. Comparative results indicated that using the induction cooker offers several benefits over traditional cooking methods, including faster cooking times, lower energy consumption, improved safety, and environmental friendliness.
