ABSTRACT
In this paper, the design & development of a DC charging unit for various engineering applications is presented. The DC Charger project is the creation of a charging system that converts AC power from the mains into a steady DC output for charging batteries and devices. The process involves using a transformer to step down the mains voltage, followed by a bridge rectifier that converts AC to pulsating DC. Smoothing capacitors then refine the DC waveform, which is further stabilized by voltage regulators to provide a consistent 12V output. A relay that manages the charging process. When the battery is fully charged, the relay disconnects the charging current. LED indicators provide visual cues for charging status. Protection mechanisms prevent issues such as overcurrent and overvoltage, ensuring safety. The project teaches about the basics of DC power electronics and how to design, build, components, and test a DC charger. It will also give you the opportunity to apply your skills in electronics and problem-solving. The work carried out is the second semester mini-project by the students of Electronics & Communication Engineering under the guidance of the faculties.
