DESIGN AND SIMULATION OF A PHOTOVOLTAIC-BASED ENERGY SYSTEM FOR MOBILE DEVICE CHARGERS AT PUBLIC PLACE

摘要

In modern times, the mobile devices and renewable energy have become so popular in our society. However, there was one important problem arises, that is the technologies cannot keep pace with technical development. The battery capacity of the mobile devices cannot satisfy the demand of customers. Therefore, a photovoltaic-based energy system for mobile device chargers is considered to be made. With the development of public transportation, that system is designed to be integrated into a bus stop for passengers' convenience. The two main parts of the control board of the system which are the buck converter and the flyback converter are simulated with real electrical components' parameters in LTspice free software. Although this design is based on Vietnam's weather conditions, it can also be applied in other countries with some further adjustments.
