In certain regions, electricity problems can arise due to various factors such as power outages and limited availability. As human needs grow, the demand for electrical energy also increases. Particularly during emergencies or disasters, it becomes crucial to ensure a continuous supply of electricity, especially for powering electronic equipment. To address this, an emergency power supply is often utilized. However, most emergency power supplies cater to single-input single-output requirements. In this paper, we explore the concept of a single-input multi-output flyback converter as an emergency power supply. This converter offers a multi-output system with one voltage level, specifically designed for charging tablets and cell phones. Through simulation, it has been observed that the system can achieve the desired output voltage level ۵V.
